[release-20.0] Upgrade the Golang version to go1.22.6

[vitess-bot]

This Pull Request bumps the Golang version to go1.22.6 and the bootstrap version to 32.2.

Do not trust the bot blindly. A thorough code review must be done to ensure all the files have been correctly modified.

There are a few manual steps remaining:

• Make sure you update the Golang version used in the previous and next release branches for the Upgrade/Downgrade tests.
• Build and Push the bootstrap images to Docker Hub, the bot cannot handle that.
• Update the ./.github/workflows/*.yml files with the newer Golang version, the bot cannot handle that due to permissions.
  • To accomplish this, run the following: go run ./go/tools/go-upgrade/go-upgrade.go upgrade workflows --go-to=1.22.6

Fix required to install percona.

v20 does not support 5.7 any more, does it? Can't we delete this and the percona57 version?

I'm ok with the 5.7 docker files being deleted in a separate PR.
