Describe the bug

#40005 broke the provider-default mechansim because the MicroProfileConfigProvider is looking for provider.default, but the general mapping of . to - has been removed.

Version

26.3

Regression

• The issue is a regression

Expected behavior

provider.default, or any key containing . should continue to work

Actual behavior

Something like --spi-password-hashing--provider-default=mycustomprovider is effectively ignored.

How to Reproduce?

Start with --spi-password-hashing--provider-default=mycustomprovider without such a provider, and you won't see an exception.

Anything else?
