## Description
This PR
- removes unmaintained `shellcode` commands, tests, and documentation
- (finally) switches to Ruff instead of Pylint (still handled by
`pre-commit`)
- fixes a few ruff/ty-found issues
This PR adds `pre-commit` to facilitate and unify the formatting of
everything in this project (code, test, docs, ci).
Aside from `.pre-commit-config.yml` and `docs/.markdownlint.yaml`, all
the other changes are purely cosmetic, applying markdownlint and fixing
here and there to make it pass.
It also creates a new CI job that'll simply execute `pre-commit` for new
PRs.
* moved `is-syscall` and `syscall-args` to gef-extras
* moved the docs for `is-syscall` and `syscall-args` to gef-extras
* [ci] changed the target binary for `nop` test
