check-docs: fix 'diagnose' and 'version'

While locally verifying an unrelated documentation change, I noticed that the 'check-docs' target displayed two warnings on the 'master' branch:

no link: git-diagnose
removed but documented: git-version

The first message was due to the introduction of 'git diagnose' [1] not including a corresponding update to 'command-list.txt'; the latter was due to 'git-version' not being built as a standalone builtin executable. This series corrects both, adding 'git-diagnose' and 'git-version' as "ancilliaryinterrogators" to 'command-list.txt' and building a 'git-version' executable.

A possible future improvement to avoid this sort of thing could be to have 'check-docs' exit with an error if it encounters any issues (rather than printing a warning that's easily lost in build logs). For now, though, this series is restricted to fixing what's currently broken for ease of review and minimal risk.

Maintainer's note: if this would be too much of a disruption to include in v2.38 last-minute, I'm happy deferring it to the next release cycle. Alternatively, the series could be split, aiming to review & merge the first patch in this release cycle (since the 'git diagnose' error was introduced in this version) and leave the second the next cycle.

Thanks!

Add 'git diagnose' as an "ancilliaryinterrogator" (like 'git bugreport') to 'command-list.txt' in order to have it show up in 'git help -a' and avoid the "no link" warning message from the 'check-docs' Makefile target.

Like most builtins, 'version' is documented in a corresponding 'Documentation/git-version.txt' and can be invoked with 'git version'. However, the 'check-docs' Makefile target showed that it was "removed but
documented: git-version." This was cause by the fact that it is not built as a standalone 'git-version' executable, therefore appearing "removed" to 'check-docs'.

Without a precedent for documented builtins that aren't built into an executable *or* any clear reason why a standalone 'git-version' shouldn't exist, the 'check-docs' error appears to correctly identify an issue. To correct that mismatch, add 'git-version' to the 'BUILT_INS' list in the root Makefile (indicating that the 'cmd_version()' function appears in a file that is *not* 'builtin/version.c'). Additionally, to avoid the "no link" message in 'check-docs', list 'git-version' as an "ancilliaryinterrogator" (like 'git help') in 'command-list.txt'.

Very much appreciated. I agree that making it an error would have helped us a lot, and I also agree with you that it can be left for the next cycle.

Will queue. Thanks.
