parser: force a `ValueError` to bytes before passing to `error.ParseError`

I'm not sure what changed before pytype 09-09-2021 (from 04-15-2021), but this
started getting flagged.  I think there's a pytype bug here, because I don't
see how `.lower()` can be getting called on a `ValueError` after it is forced to
a byte string.  That's suppressed for now to make progress.

This fixes:

    File "/mnt/c/Users/Matt/hg/mercurial/parser.py", line 219, in unescapestr: Function bytestr.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, ints: Iterable[int])
      Actually passed: (self, ints: ValueError)
      Attributes of protocol Iterable[int] are not implemented on ValueError: __iter__
    File "/mnt/c/Users/Matt/hg/mercurial/parser.py", line 219, in unescapestr: No attribute 'lower' on ValueError [attribute-error]
      In Union[ValueError, mercurial.pycompat.bytestr]

Testing tagging with the EOL extension

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > eol =
  > 
  > [eol]
  > native = CRLF
  > EOF

setup repository

  $ hg init repo
  $ cd repo
  $ cat > .hgeol <<EOF
  > [patterns]
  > ** = native
  > EOF
  $ printf "first\r\nsecond\r\nthird\r\n" > a.txt
  $ hg commit --addremove -m 'checkin'
  adding .hgeol
  adding a.txt

Tag:

  $ hg tag 1.0

Rewrite .hgtags file as it would look on a new checkout:

  $ hg update -q null
  $ hg update -q

Touch .hgtags file again:

  $ hg tag 2.0

  $ cd ..
