[watch] allow ignoring non-existing paths

[Gentle]

Trunk.toml allows to provide paths that should be ignored by trunk watch and trunk serve, but the way this is currently implemented requires the paths to actually exist so you can ignore them. This causes issues when you want to ignore optional files (like editor specific temporary or configuration files)

my proposal would be to allow non-existing paths in ignore
