## Summary
Fixes #12606.

Two options considered, thanks to @zanieb's guidance are:
1. Special-casing on parse error and encountering the `environment.yml`
filename, possibly at `RequirementsTxt::parse`
2. Adding a new `RequirementsSource::EnvironmentYml` variant and
erroring on `RequirementSpecification::from_source`

I went with the latter for the following reasons:
- This edge case is explicitly modelled within the type system. However,
it changes the semantics of `RequirementsSource` to also model
_unsupported_ sources.
- (**Separation of concerns**) The special-casing would occur in the
`uv-requirements-txt` crate, which seems to be relatively deep in the
guts of the codebase. In my opinion, maintainers working in
`uv-requirements-txt` would reasonably assume the input file to be a
`requirements.txt` file, instead of having to be concerned with it being
another file format (`environment.yml`, `pyproject.toml`, etc.)

## Test Plan
Manually tested as follows:
```sh
>>> cargo run -- pip install -r environment.yml
error: Conda environment file `environment.yml` is not supported

>>> cargo run -- add -r environment.yml
error: Conda environment file `environment.yml` is not supported
``` 

If you can point me to the appropriate test module, I can write up tests
for these to use `insta`.
