chore: upgrade kustomize to 4.5.5

[KENNYSOFT]

Upgrade kustomize to 4.5.5, which introduced a lot of performance improvements: kubernetes-sigs/kustomize#4568.

Used script after download files from https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv4.5.5:

find kustomize*.gz | while read file
do
  sha256sum $file | sed 's/^  //' | sed 's/ \*/  /' | sed -E 's/v([0-9]+)/\1/' > $(echo $file | sed -E 's/v([0-9]+)/\1/').sha256
done

Also, unified checksum files ending to LF.

QUESTION: Do I need to explicitly write this to release notes even if it's bumping one minor version? #8227 (review) This comment says if two minor versions then should be, but I don't know for one.

Don't know why integration tests in k3s v1.24.1 result to timeout. 🤔

It seems to have become flakey when 1.24.1 was introduced as a tested version. It's unrelated to your changes.

@KENNYSOFT thanks for the PR! I'd recommend creating a 2.4-to-2.5 upgrade notes doc and add this upgrade.

I don't think we'd want to cherry-pick the upgrade into 2.4.

@KENNYSOFT updated the branch to fix the CI failure. Be sure to git pull before making any additional changes. :-)

Done, thanks!

lgtm! Will wait for a second review to merge, since it's a significant change.

LGTM.
I Agree that it shouldn't be cherry-picked in 2.4. I think it is good to merge this now to allow identifying 2.5 issues early.
