Martin Ågren 32c6fff4b8 cmd-list.perl: fix identifying man sections ...

We attribute each documentation text file to a man section by finding a
line in the file that looks like "gitfoo(<digit>)". Commit cc75e556a9
("scalar: add to 'git help -a' command list", 2022-09-02) updated this
logic to look not only for "gitfoo" but also "scalarfoo". In doing so,
it forgot to account for the fact that after the updated regex has found
a match, the man section is no longer to be found in `$1` but now lives
in `$2`.

This makes our git(1) manpage look as follows:

  Main porcelain commands
       git-add(git)
           Add file contents to the index.

  [...]

       gitk(git)
           The Git repository browser.

       scalar(scalar)
           A tool for managing large Git repositories.

Restore the man sections by not capturing the (git|scalar) part of the
match into `$1`.

As noted by Ævar [1], we could even match any "foo" rather than just
"gitfoo" and "scalarfoo", but that's a larger change. For now, just fix
the regression in cc75e556a9.
