[docs] Misleading reference to `ENVDIR` in the description of the `tox devenv` command

[webknjaz]

This paragraph https://tox.wiki/en/4.21.2/cli_interface.html#tox-devenv-(d) references a mysterious ENVDIR which seems to be copy-pasted from https://tox.wiki/en/4.21.2/cli_interface.html#tox-legacy-(le). The command example does not have a ENVDIR placeholder, but has a [path]. Is that what was supposed to be in the description?

[gaborbernat]

Yeah small docs bug, should be path.

[webknjaz]

@gaborbernat perhaps mark as hacktoberfest and good first issue?

[gaborbernat]

We do not have either label setup 🤔

[webknjaz]

Oh, I didn't realize. The repo itself is labeled, though.

[gaborbernat]

Fixed it 👍
