Allow Ultranormalized Names To Be Released Without Prohibition

[Thespi-Brain]

What's the problem this feature will solve?
Names that are similar due to ultra-normalization currently have to be "prohibited" and then released. Changing the function to just allow release of the name without prohibition will simplify the process. There are quite a few PEP 541 issues that are tagged "similar name" issues where a user is blocked from getting a package name that they want due to ultra normalization collisions. Having a function to just release the names will speed up resolution of the PEP 541 issues.

Describe the solution you'd like
A function that allows release of an ultra-normalized name without prohibiting it first.

Additional context
None
