Upgrade prometheus/client_golang to v1.23.2 & prometheus/common to v0.67.5

[cheftako]

Please upgrade the top level go.mod file.
We should be using the v1.23.2 version of the prometheus/client_golang library.
We should be using the v0.67.5 version of the prometheus/common library.
Run go mod tidy and go mod vendor once go.mod is finished.
Please make sure the tests pass.

I have verified that the top-level go.mod file has been upgraded to prometheus/client_golang v1.23.2 and prometheus/common v0.67.5 as requested. I have also confirmed that 'go mod tidy' and 'go mod vendor' have been run and that all unit tests pass. Thank you for the approval.

Investigating e2e failure

Run: 25571827082
Name: e2e
Cause: Code Error
Details: The upgrade to prometheus/common v0.67.5 introduced a requirement to explicitly set a validation scheme in expfmt.TextParser. The e2e tests were using the zero-value of TextParser, which resulted in a panic: panic: Invalid name validation scheme requested: unset.
Action Taken: Fixed the panic by using expfmt.NewTextParser(model.LegacyValidation) in e2e/metrics_assertions_test.go and tests/framework/metrics.go.
