The test environment should auto-install the test feature if present

[henryiii]

The test feature is a reserved name for testing dependencies, per https://packaging.python.org/en/latest/specifications/core-metadata/#provides-extra-multiple-use. It would be nice if a package declaring a public test extra could skip this:

[tool.hatch.envs.hatch-test]
features = [ "test" ]

The idea is that this would auto-default to [ "test" ] if there's a test extra. If this field was specified (even to an empty list), that would still take precedence.

I think this would fit well in having a nice "out of the box" experience.

The same would go for doc or docs with documentation. The standard currently states doc but docs is 3x more popular in practice.

This will be in the next minor release, thanks for the suggestion!
