Pass extra args for friendlier CSpell UX (#2271) (#2275)

Pass --show-context to show the text surrounding a misspelling,
--show-suggestions to show best guesses of the correct spelling,
and --no-must-find-files to suppress errors when there are no files to
spell check. This prevents CSpell from complaining when MegaLinter is
run incrementally but no spell-checked files were modified.
