- Updated name to align, and differentate from new 'XQueries' clases.
- Removed old sketchy base class with app resolving workarounds, to a
proper injection-based approach.
- Also fixed wrong translation text used in PageQueries.
Swapped back handling to instead be pre-determined instead of being
based upon session/referrer which would cause inconsistent results when
referrer data was not available (redirect to app-loaded images/files).
To support, this adds a mechansism to provide a URL through request
data.
Also cleaned up some imports in code while making changes.
Closes#4656.
- Changed use of array spread since it was not supported in PHP8.0.
- Updated issue templates based to reduce less valueable fields, update
some details, and try to help bug reports be more focused on bugs.
- Updated readme with peertube link and attribution advistory for
translations PRs.
