Simplify author regex in update-authors.py

Before this change, update-authors.py would use a more complicated regex
pattern. That pattern would sometimes fail to match anything and result
in match() returning None followed by an AttributeError.

The old regex pattern already assumed that there would be a "\t" before
the information that we’re looking for. This new pattern starts by
looking for the "\t" (rather than worrying about what comes before the
"\t").

The new pattern also simplifies the rules for matching an author’s name
and email. If we really want to enforce rules like “the author’s name
must only use word characters and spaces” or “the author’s email must
not contain ‘>’”, then we should add a CI check or something.

Fixes #3109.
