Linter additions & fixes, Dependency updates, and more!

Added

• linter: --no-error-on-unmatched-pattern argument to not exit with an error if no files are matched (default: false) (#639). Thanks @PascalFrenz!
• linter: gitlab reporter (#624). Thanks @benedikt-bartscher!

Fixed

• linter: adding-field-with-default now checks that the postgres version is <= 11 before reporting an error for non-volatile defaults (#637). Thanks @ermakov-oleg!

• linter: github commenting truncates when too large (#605). Thanks @ienugr!

• parser: parsing path's named operator now works (#640).

  Previously the following would error:

  create table operator();

• squawk_syntax: ast::BinExpr lhs & rhs properties now work correctly (#634).

• internal: bumped a bunch of outdated JS & Rust dependencies (#630), (#631), (#632), (#633).
