feat: match additional lockfiles for lock type

[joshsleeper]

changes

• adding a few common lockfile patterns to the lock type
  • .terraform.lock.hcl for opentofu/terraform provider dependency locking
    • https://opentofu.org/docs/language/files/dependency-lock/
    • https://developer.hashicorp.com/terraform/language/files/dependency-lock
  • gradle.lockfile for gradle dependency locking in the java ecosystem
    • https://docs.gradle.org/current/userguide/dependency_locking.html#sec:generate-locks
  • pnpm-lock.yaml for pnpm dependency locking in the npm ecosystem
    • https://pnpm.io/feature-comparison
    • this is the one that actually convinced me to open this, as we use pnpm at work and I was surprised that it wasn't matched by the lock type already
  • pylock*.toml for pypi dependency locking in the near-future python ecosystem
    • https://packaging.python.org/en/latest/specifications/pylock-toml/
    • the PEP is accepted and partially implemented in tools such as pip and uv, but still not fleshed out enough that it's actively used by said tools yet, but I believe the expectation is that this will become The One Python Lockfile To Rule Them All ™️ at some point

validation

I created a non-empty junk file in a local locktest/ dir for each of the added patterns and verified that a local run included them
