feat: Add a RNG Action

[laurentsimon]

This is part of #500 in order to generate random names.
In a follow-up PR, I will use names as some-name-<random>

This is cool!

The project needs a README with all the actions.

[laurentsimon]

Any feedback on the name of the Action. PRNG makes it sound like a cryptographic PNRG, but it's not intended to be used as such. I think I'll rename to RNG instead :)

After thinking about this should probably be written in go. This is adding tech debt.

Yeah, I'd like to reduce our use of inline shell scripts if we can too. Though it's pretty small so I could go either way.

I think installing Go compiler and compiling the program will add too much overhead to these kind of small actions. And we also really want to avoid having to do a checkout of the repository as part of the action as there are version skew and security implications.

If we want to write them in another language I think the best choice would probably be writing it in Javascript. It works similarly to the Dockerfile actions, but doesn't require building the image every time before running it.

I'm also leaning towards TS. On the other hand, the script is really small. I'm not even sure I'd call it "tech debt".
