centralize ci action versions

[rochdev]

What does this PR do?

Centralize CI action versions.

Motivation

These hashes are otherwise repeated dozens of times in many files and might deviate over time, when in reality what we really want is to use latest. Having the version in a single place makes it a lot easier to update everything at once and ensure consistency.

Going to close this as there is no way to handle actions/checkout and it's one of the biggest offenders.
