Spring Security metric names should not contain dashes

[Ducius6]

When upgrading to Spring Boot 3 we had issue in new spring security metrics exposed with Micrometer. Issue seems to be that these metrics end up having "-" in it's name.
And since we are using prometheus, scraping/parsing of metrics did not work since prometheus can't have dash in it's metric name.

Exact metric that was causing the issue is "spring_security_filterchains_session_url-encoding_before_total" which is located in ObservationFilterChainDecorator.class.

Should naming of these metrics change so it can be used with prometheus?

Hi, @Ducius6. Yes, let's make the change and remove the - in url-encoding and eager-create.

Are you able to provide a PR?

[Ducius6]

Yes, sure. Will do!
