Re-enable color for neotest

[Jasha10]

Feature description

PR #461 disabled color output for neotest by passing --color=never to cargo.
This worked around an issue where one test failure caused all succeeding tests to be marked as failed (#460).

When I set --color=always in the lua/neotest/init.lua file, I'm not currently able to reproduce the issue where one failure caused succeeding tests to be marked as failed. Would it be possible to re-enable color in the rustaceanvim neotest adapter (or make color configurable)?

Hey 👋

sure, I could put it behind a config option.
I'm busy right now, but perhaps I'll find some time later this week.
Otherwise, PRs are welcome 😄
