Update SwiftLint (0.50.3) version in Dockerfile used in danger-swift-with-swiftlint container.

[JaviLorbada]

This PR aims to update SwiftLint to version 0.50.3 used in danger-swift-with-swiftlint docker container.

SwiftLint release: https://github.com/realm/SwiftLint/releases/tag/0.50.3

[JaviLorbada]

@f-meloni could we try to create a new version of the danger-swift-with-swiftlint container and bump swiftlint to 0.50.3?

If something fails while building the container we can easily roll back, although I tried docker build and everything seemed fine. Thanks so much.

[f-meloni]

Yes, I'm currently not at home, but will be back and release beginning of next week 🙂

[JaviLorbada]

Awesome! Thank you very much!

[JaviLorbada]

Thanks for merging @f-meloni! 🙏🏼 Is there any date scheduled for the next release? Is there a way I can fetch a docker container including these changes? Thank you.

[f-meloni]

I have done the release, but the build failed because the new swiftlint requires bazel

[JaviLorbada]

Oh, no! I had no idea about that, sorry it broke the release.

[f-meloni]

No problem at all :) it can still be fixed or reverted, everything else but the container with swiftlint should be working ok

Any idea what could be the solution here to allow using the 3.16.0 container with SwiftLint? I believe Bazel can be installed via npm (npm install -g @bazel/bazelisk) which we already use to install Danger-JS. Alterrnatively, it can be installed using apt-get but the process looks a big more complicated (https://bazel.build/install/ubuntu). Would adding this extra step to the Dockerfile help?

I had tried with apt get before, and had some issues with the versioning.
I have tried npm install -g @bazel/bazelisk and that seemed to work well, but then I found out that I also need ruby 😢

After installing that and setting CC=clang as required, I still get
