get_oer2go_catalog:52: SyntaxWarning: invalid escape sequence '\<' php_parser = re.compile('\<\?php echo .+? \?>')

[holta]

Is this increasingly common new warning (seen commonly in recent months) possibly a result of Ubuntu 24.04's Python 3.12 being more strict than prior versions of Python ??

Here's an example, that occurs every time root runs ./install in /opt/iiab/iiab-admin-console :

...
Finished writing to /etc/iiab/kiwix_catalog.json
SUCCESS/opt/admin/cmdsrv/scripts/get_oer2go_catalog:52: SyntaxWarning: invalid escape sequence '\<'
  php_parser = re.compile('\<\?php echo .+? \?>')
Skipping module not needed by Internet in a Box 12 en-PhET
...

It also happens when root runs iiab-get-oer2go-cat all alone:

/opt/admin/cmdsrv/scripts/get_oer2go_catalog:52: SyntaxWarning: invalid escape sequence '\<'
  php_parser = re.compile('\<\?php echo .+? \?>')

As a result of this line... that presumably needs a quick cleanup?
