Incorrect 'Validate schema file' step

[x1z53]

The original unformatted file is currently being submitted for validation, which causes the following error:

/usr/src/RPM/BUILD/gradia-1.10.0/data/be.alexandervanhee.gradia.gschema.xml:4:1  Error on line 4 char 1: A path, if given, must begin and end with a slash.  --strict was specified; exiting.

My fix:
(Since I'm not well versed in Meson, I decided not to open PR, as there might be a better solution.)
