Ignore local config/ directory

[jesserockz]

What does this implement/fix?

Adds config/ to .gitignore so a local config/ working directory (alongside the already-ignored configs/) isn't accidentally committed.

All ESPHome documentation refers to config as the directory so it makes sense to add this here too
