Fix /add relnote for PCRE2 issues

I tried running `/add relnote` for the most recent PCRE2 issue in
git-for-windows/git#5398 (comment)
but it failed:

  The following deployment(s) are missing:

  * https://wingit.blob.core.windows.net/i686/pcre2-pcre2-10.45-1-i686.pkg.tar.xz
  * https://wingit.blob.core.windows.net/x86-64/pcre2-pcre2-10.45-1-x86_64.pkg.tar.xz
  * https://wingit.blob.core.windows.net/i686/mingw-w64-i686-pcre2-pcre2-10.45-1-any.pkg.tar.xz
  * https://wingit.blob.core.windows.net/x86-64/mingw-w64-x86_64-pcre2-pcre2-10.45-1-any.pkg.tar.xz

Clearly, GitForWindowsHelper was parsing the version incorrectly. Let's
fix that.
