Bump profiler-cli version to 0.3.0 (#6104)

Pass `--use-env-proxy` only when the node version is >= 24 (#6064)

See also individual commit messages.
`--use-env-proxy` was added in Node.js 24, and I added that in #6003 to
make sandboxed anvironments work. But the cli now stopped working for
the users who has node version that's below 24. This PR adds this flag
conditionally if the node version is above that.

Note that sandboxed environments might not work for node < 24. But I
added a warning log to the users explaining that.

Bump profiler-cli version to 0.2.0 (#6059)

Bump profiler cli version to 0.1.0 (#5996)

This PR bumps the profiler-cli to 0.1.0 for the first npm non-alpha
release!

I will publish the release once this PR lands and then add a tag for
this release.

Currently the publishing flow is documented in
https://github.com/firefox-devtools/profiler/blob/main/docs-developer/deploying.md#publishing-profiler-cli-to-npm,
but it's pretty manual. It might be good to make this automated with
some github actions. But this is a todo for later time for now.
