so that meta.description examples shown in the documentation
align with recommendations given in the "Meta attributes" section
in pkgs/README.md.
The changes were made with the following commands:
nix run nixpkgs#silver-searcher -- -l0 'description\s*=\s*"([Aa]n?|[Tt]he)\s' doc \
| xargs -0 nix run nixpkgs#gnused -- -i '' -Ee '/description/s/"([Aa]n?|[Tt]he)\s(.)/"\U\2/'
nix run nixpkgs#silver-searcher -- -l0 'description\s*=\s*".*\."' doc \
| xargs -0 nix run nixpkgs#gnused -- -i '' -Ee '/description/s/\."/"/'
`meta.sourceProvenance` has its own level 2 heading at the bottom of the file,
but unlike the other meta-attributes it doesn't have a level 3 heading under the
"Standard meta-attributes" section. Readers looking at the list of subheadings
directly under the "Standard meta-attributes" section header may not realize
that `meta.sourceProvenance` exists unless they scroll down to the bottom of the
page.
This commit adds a level 3 heading for sourceProvenance under "Standard
meta-attributes".
* doc: add stdenv passthru chapter
Broad strokes:
- create the chapter
- move existing stdenv passthru coverage into it
- move out-of-place coverage of passthru.tests from the stdenv meta chapter into it
- (try to) apply 1-sentence-per-line to text I've touched
- add legacy anchors for everything moved
- update existing links to the new anchors
- add tentative motivating text
- make nixpkgs-internal links relative/branchless
razor: if it is only ever needed by contributors, which is likely if links
refer to the latest revision of the source code, then it's for
the contributor guide

Following [Best Practices](https://nix.dev/guides/best-practices#with-scopes),
`with` is a problematic language construction and should be avoided.
Usually it is employed like a "factorization": `[ X.A X.B X.C X.D ]` is written
`with X; [ A B C D ]`.
However, as shown in the link above, the syntatical rules of `with` are not so
intuitive, and this "distributive rule" is very selective, in the sense that
`with X; [ A B C D ]` is not equivalent to `[ X.A X.B X.C X.D ]`.
However, this factorization is still useful to "squeeze" some code, especially
in lists like `meta.maintainers`.
On the other hand, it becomes less justifiable in bigger scopes. This is
especially true in cases like `with lib;` in the top of expression and in sets
like `meta = with lib; { . . . }`.
That being said, this patch removes most of example code in the current
documentation.
The exceptions are, for now
- doc/functions/generators.section.md
- doc/languages-frameworks/coq.section.md
because, well, they are way more complicated, and I couldn't parse them
mentally - yet another reason why `with` should be avoided!

The `pcre` library is "now at end of life, and is no longer being
maintained," according to the upstream maintainers. Accordingly, we
should replace uses of `pcre` with its actively maintained successor,
`pcre2`, wherever possible .
Update instructions for manual build phases execution via `nix-shell` to
cover all phases. There is no easy way of getting those commands, so it
makes a sense to have them all properly documented.
While the word 'simply' is usually added to encourage readers, it often has the
opposite effect and may even appear condescending, especially when the reader
runs into trouble trying to apply the suggestions from the documentation. It is
almost always an improvement to simply drop the word from the sentence.
(there are more possible improvements like this, we can apply those in separate
PRs)
