update actions and docker images

[Migelo]

The only non-trivial change is updating actions/upload-artifact from v2 to v4, source. They don't allow for artifacts with the same name being uploaded and overwriting each other. This happened in the linux-ci workflow where different gcc versions were used but the artifact they produced had the same name, making the v4 action fail. I fixed it by creating a unique name for each gcc version.

    -  name: et-client-${{matrix.os}}
    +  name: et-client-${{matrix.os}}-gcc${{matrix.gcc}}

Thanks!

Great! Would you be interested in adding renovatebot to the repo? I used it to get these updates done. With the configuration below the bot creates an issue that acts as the dashboard and then makes pull requests when it detects a new version of something. If tests pass it will then merge minor version bumps with major version bumps requiring a manual merge.
