…build#16586) This fixes pantsbuild#16451 by continuing the color half of pantsbuild#16488 (terminal width). It does this by forcing mypy to always include color escapes, and then stripping them out in pants, based on the [GLOBAL].colors setting. This seems to only be possible via an undocumented environment variable: `MYPY_FORCE_COLOR`: python/mypy#7771, https://github.com/python/mypy/blob/03638dd670373db0b8f00cc3bcec256d09729d06/mypy/util.py#L543 Doing this also requires setting `TERM=linux` so that curses can find appropriate info in the terminfo database.
