Add musl-gcc as dependency (#21366)

This addition comes after attempting building Zed from source.

As part of the process, one of the components (a crate I presume) called
`ring` failed to compile due to the following sequence of console
messages:

```log
warning: [email protected]: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?
warning: [email protected]: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?

error: failed to run custom build command for `ring v0.17.8`
```

Adding this library should help fix the issue on Fedora 41 at least, and
possibly will help fixing it for other RedHat based distributions as
well.

Closes #ISSUE
