Set ComponentSLIs feature as GA

[Jefftree]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

ComponentSLIs has been GA since 1.29 https://kubernetes.io/docs/reference/instrumentation/slis/, however the feature was not listed as GA in the feature gates. I originally removed this feature #127787, but that creates an inconsistency in feature gate emulation for 1.31 (ref: #128036 (comment)).

The safest option is to mark this feature as GA and remove in 3 releases. The caveat being that the "GA" version described in this file is inaccurate compared to the actual feature graduation date. This also unblocks #128138

Which issue(s) this PR fixes:
