gobject-introspection: Update version from 1.68.0 to 1.76.1

Currently, `g-ir-scanner` fails to run – probably due to updating our
Python environment.

    $ /usr/bin/g-ir-scanner --version
    Traceback (most recent call last):
      File "/usr/bin/g-ir-scanner", line 98, in <module>
        from giscanner.scannermain import scanner_main
      File "/usr/lib/gobject-introspection/giscanner/scannermain.py", line 35, in <module>
        from giscanner.ast import Include, Namespace
      File "/usr/lib/gobject-introspection/giscanner/ast.py", line 29, in <module>
        from .sourcescanner import CTYPE_TYPEDEF, CSYMBOL_TYPE_TYPEDEF
      File "/usr/lib/gobject-introspection/giscanner/sourcescanner.py", line 34, in <module>
        from giscanner._giscanner import SourceScanner as CSourceScanner
    ModuleNotFoundError: No module named 'giscanner._giscanner'

So, update to the latest release, so it’s also rebuild against our current
system Python 3.10.10.
