fix: disable git hooks in protonmail sg_only Dockerfiles

Protonmail/webclients repos have husky git hooks that run yarn on
commit. After source truncation, package.json is empty, causing
yarn to fail. Remove .husky and .git/hooks before the truncation
commit to prevent this.

Affected: protonmail-dropdown-sizing-fix-001, protonmail-holiday-
calendar-fix-001, protonmail-conv-testhooks-fix-001.
