[CI] Fix GitHub Action Release Deprecation

[SeanNaren]

🐛 Bug

GitHub Actions deprecated something within our current CI for docker releases: https://github.com/PyTorchLightning/pytorch-lightning/actions/runs/424422351

@Borda already found what needs to change:

https://https://github.com/PyTorchLightning/pytorch-lightning/blob/597dfa174c9488771044ae5b3496f9ed94f9354a/.github/workflows/release-docker.yml#L29

https://github.com/PyTorchLightning/pytorch-lightning/blob/597dfa174c9488771044ae5b3496f9ed94f9354a/.github/workflows/ci_dockers.yml#L85

[Borda]

this is the deprecated call
https://https://github.com/PyTorchLightning/pytorch-lightning/blob/597dfa174c9488771044ae5b3496f9ed94f9354a/.github/workflows/release-docker.yml#L29

this is the new call like
https://github.com/PyTorchLightning/pytorch-lightning/blob/597dfa174c9488771044ae5b3496f9ed94f9354a/.github/workflows/ci_dockers.yml#L85

@InCogNiTo124 is interested in...

[InCogNiTo124]

@Borda yeah, I'll try to get it done this week :))

[Borda]

@InCogNiTo124 how is it going, do you need some help?
we would like to have in for the next bug-fix release and ideally test it with next RC over weekend :]

@Borda due to life I wasn't able to start this, but I will hopefully get it done tmrw. Seems trivial
