Subject: [PATCH] Protect against accidental SOLC_VERSION clash from workflow

Users may set SOLC_VERSION in the workflow and cause hard-to-diagnose
problems in the action (see crytic/slither-action#19). To avoid that
from happening, unset SOLC_VERSION early on. If the user desires
to change the solc version, they can always use the `solc-version`
action option.
