Update to Go 1.25

[Sovietaced]

Why are the changes needed?

Go 1.25 includes performance improvements (changes to default behavior of GOMAXPROCS) and we need to keep Go up to date in order to keep some of our dependencies up to date.

What changes were proposed in this pull request?

• Update Go to 1.25
• Update golanci-lint to version 2 since version 1 only supports up to Go 1.24. golangci-lint configuration files have been migrated to keep as close to the existing behavior as possible using golangci-lint migrate. See the migration guide

Dependency review fails due to an ongoing request to update gRPC.

How was this patch tested?

Existing unit / integration tests

This is important to improve the readability of release notes.
