fix(pick): update CLI tools to not force --no-follow flag

Details:
- By default `rg` (and probably `fd`) do not follow links, which is good
  for performance. So forcing the flag is not needed and is too
    restrictive for users that *do* want to follow symbolic links via
    CLI specific config.

Resolve #1969
