fix(coffee): fix completion bug on missing `coffee` command (#10759)

This commit fixes the error

  _coffee:49: bad math expression: operand expected at `< 2 '

when the coffee command is missing or the `coffee --version` command fails.

It also uses is-at-least to check for the cut-off version for suggesting
`--lint` and `--require` arguments, instead of using `cut` multiple times.

Fixes #10759
