Site Health: Improve fonts directory check.

This changeset enhances the filesystem checks in the Site Health debug data by addressing the following:
- Existence Check: Before checking if the fonts directory is writable, it first verifies whether the directory exists.
- Improved Messaging: If the fonts directory does not exist, the debug output now reflects this scenario as "Does not exist". If the directory exists, it shows whether it is writable or not.

Fixes #62633.
