Add script aliases (experimental)

[ipince]

Summary

This is just a quick and dirty experiment. It adds alias <script>=<path-to-script> for every script. This can unlock two potentially useful things:

1. A script can call another script. I tested this and it works just fine.
2. When a user is in devbox shell, they could potentially just type <script> instead of devbox run <script> and execute the script they want. That said, if you run it directly, the script would be executing within the devbox shell environment, so it may not behave exactly the same as if it were run with devbox run, which is a bit more strict/pure. Of course, the user could still run with devbox run if they wanted the other behavior.

This is just a proof-of-concept. I don't know if alias will work with different shells--need to test. I'd also need to add a guard to .hook.sh, to prevent the hooks from being run multiple times, which isn't a problem today.

How was it tested?

Tested a script can call another script, and that I can call a script inside a shell if I manually source .hooks.sh. The sourcing would have to be automatic. Haven't tested that or cross-shell support.

Oh and, of course, if a script has the same name as some other command, then the script would shadow/take precedence.

If you add a feature flag we can go ahead and merge it

RC because this is old.

Thoughts on putting this behind a devbox.json setting? (so opt-in ?)
