env.requires does not support context formatting

[soulmerge]

I want to install an environment plugin from the local file system. My pyproject.toml contains the following:

[tool.hatch.metadata]
allow-direct-references = true

[tool.hatch.env]
requires = [
  "my-hatch-plugin @ {root:uri}/tools/my-hatch-plugin",
]

But it seems the env.requires value does not support context formatting.

I have also seen this other issue #1199 related to context formatting, which also has an open pull request #1472. I would be willing to contribute a PR for this issue here, using the changes in the other PR as reference.
