Issue #32: Updated logging function declarations

[niko-hoogeveen]

Closes Issue #32.

I've added the proper return types for functions in logging/loggerbase.php to fix the fatal errors occurring in PHPUnit tests.

Environment Details

• PHP 8.1
• MOODLE 4.5
• Postgres 16.0

Branch that has the issue:

• MOODLE_405_STABLE

How to recreate the issue?

1. Deploy a local Moodle 4.5 instance (with this plugin installed on branch MOODLE_405_STABLE)
2. Initialize PHPUnit testing environment
3. Run vendor/bin/phpunit -> the error only appears when running the full list of unit tests. Running vendor/bin/phpunit --testsuite mod_collaborate_testsuite yields no errors.

Actual Output

Moodle 4.5.5 (Build: 20250609)
Php: 8.1.2.1.2.22, pgsql: 16.9 (Debian 16.9-1.pgdg120+1), OS: Linux 6.8.0-1021-aws x86_64
PHPUnit 9.6.18 by Sebastian Bergmann and contributors.

Checkout to my branch, and you should see no PHP Fatal errors related to mod_collaborate when running vendor/bin/phpunit.
