Use sourceforge mirror for PCRE2 as FTP one has been removed
As mentioned in https://www.pcre.org/
Note that the former ftp.pcre.org FTP site is no longer available. You will need to update any scripts that download PCRE source code to download via HTTPS, Git, or Subversion from the new home on GitHub instead.
However, PCRE2 10.33 is not available on GitHub as it is relatively old. Hence, using the "unofficial" sourceforge mirror. We're using this mirror in omnibus-gitlab also.
When we move to a newer PCRE2, we can move to GitHub releases also.
