Remove unused dependencies

The dependabot file was matching on tree-sitter crates - that's a relic
from v0.6.0 and lower where grammars were regular dependencies.

The remaining changes are unused crates that were forgotten about during
shuffles like moving path canonicalization from helix-core to
helix-loader (and then again from helix-loader to helix-stdx).
