"hatch test -py 3.14 --cover" crashes with IndexError #2081
Description
Even though I have 3.14 included in tool.hatch.envs.test.matrix in pyproject.toml,
I get a crash when running hatch test -py 3.14 --cover. It's specific to 3.14 and --cover.
$ hatch --version
Hatch, version 1.14.2
[[tool.hatch.envs.test.matrix]]
python = ["3.12", "3.13", "3.14"]
$ hatch test -py 3.14 --cover

PR #2080 fixes it for me.
