maintenance: upgrade to TypeScript 5, Oclif 4, node 18+

[paulRbr]

This is basically a re-write from scratch using a newly generated package from Oclif v4 due to a too big of a jump from Oclif v1 to oclif v4.

I've then copied files from our CLI one by one making sure compilation (and features) work.

There are still some work to be done: (all done 🎉)

• preview cmd
• diff cmd
• deploy cmd
• overlay cmd
• Tests
  • unit
  • commands (done but there's something I'm missing they don't run!)
  • integration

Notes for the reviewer

It's a big PR, sorry for that, we can do a pair-review if you feel like it 🤗.

Also, there are a few things I had to adapt in the CLI to make this current upgrade:

• I couldn't get the open node package to work (it was included in oclif's fancy-ux in v1 but isn't part of oclif anymore). This lead me to comment (and thus disable the --open flag features of the CLI) it works!
• I could't find a way to test a “waiting” command (the bump preview --live one) because the mocha test process never ends due to the command “waiting”. I tried with mocking the stdin (as described here) but I don't think an “exit signal” character exists which I can send to stdin to stop the running command. This lead me to comment the related test.

Closes #448

feedbacks following live test:

• node v20 is required as minimal version

bump preview: all good
option -o does not work, IMO it can be removed

bump preview: all good

bump deploy: all good
in hub, when interactive mode is selected and api filename should be removed, I have an error (only when flag --auto-create was missing, maybe a false positive)

bump diff : all good

bump overlay: all good

I'm very impressed by this new version of CLI, well done 👏

As discussed in sync, there was a bug when selecting multiple times the same file: I've fixed the code to only present files that have not yet been selected (and thus the error should not be possible anymore)

• node v20 is required as minimal version

Changed the minimal version in the package.json ✅
