fix(tvix): remove disruptive .envrc file r/5418
This .envrc file causes additional software to be loaded, but there is
no way to opt-out even if the software is not desired:

1. If I opt-in (i.e. `direnv allow`) the file, additional stuff that I
   don't need is injected into my environment in a blocking way.

2. If I opt-out, *all* of the depot configuration (including `mg`) is
   unloaded, as direnv configurations do not trivially nest.

I have to work around this constantly by making the file contain just
the line `source_up` and then setting `--assume-unchanged` on the git
index to avoid accidentally committing the file changes.

This is kind of silly, the people who *want* this stuff to be loaded
should devise a mechanism that loads it automatically but is opt-in.

This could be done e.g. by gating something on environment variables,
or having a shell hook, or whatever. Breaking expectations that hold
elsewhere in depot is not okay, however.

If you manually want a shell for a project, run `mg shell` either with
a target specification for that project (e.g. `mg shell //tvix/store`)
or in the project's folder.

You can also just use standard nix-shell invocations.
