v3: CI: Pin cargo-release and cargo-semver-checks

[joncinque]

Problem

cargo-semver-checks now requires Rust 1.89, but the v3 branch is still on 1.88.

Summary of changes

Pin cargo-semver-checks to the last known working version. Do the same with cargo-release, since that just upgraded to Rust 1.89.

Ha nice, I was just looking into this / about to create a PR when I saw yours.

Should we also remove this statement so that we get the semver check to run in normal CI ? I didn't git blame my way to see why it was disabled in the first place, but the comment there would suggest we could re-enable it now

solana-sdk/.github/workflows/main.yml

Lines 186 to 204 in f544553

	if: false # enable after 2.2.0 is cut
	name: Check semver
	runs-on: ubuntu-latest
	needs: [sanity]
	steps:
	- name: Git Checkout
	uses: actions/checkout@v4
	- name: Setup Environment
	uses: ./.github/actions/setup
	with:
	stable-toolchain: true
	cargo-cache-key: cargo-stable-semver
	cargo-cache-fallback-key: cargo-stable
	- name: Install cargo-semver-checks
	uses: taiki-e/cache-cargo-install-action@v2
	with:
	tool: cargo-semver-checks

For example, I can see that Check semver was skipped for this PR:

Running semver-checks on every PR can be very noisy, especially when the repo is in a broken (EDIT: meaning, contains breaking changes) state, so we've decided to only run it on publish. I'll remove that check.

Feel free to approve this PR if you want though 😉

Looks great!

Got it, figured there may be some context I was missing

Don't mind if I do 😆
