Multisite: Introduce minimum_site_name_length filter.

Browse Source 
Prior to this change, the minimum site name length checked in `wpmu_validate_blog_signup()` was set to a fixed value of 4. The new filter allows tweaking this value, as there may be cases where shorter site names may be required.

Fixes #39676.
