♻️ Directly pass the LLVM installation directory to cpp-linter

Description

Directly pass the LLVM installation directory prepared by reusable-cpp-linter.yml to cpp-linter.

The workflow already installs the requested Clang, clang-format, clang-tidy, and clang-tools packages before invoking cpp-linter-action. Pointing the action at /usr/lib/llvm-<version>/bin makes that installed toolchain authoritative and allows callers to select Clang 23 without adding version-specific workflow logic or changing the existing input and default.

This also bypasses the numeric-version limit in cpp-linter-action v2.21.0's bundled clang-tools 1.2.0 resolver. That limit caused the jeff-mlir failure after LLVM 23 itself had installed successfully.

Validation

• uvx prek run -a
• git diff --check
• Ubuntu 24.04 amd64 container: llvm.sh 23 installed Clang 23.1.1, clang-format 23.1.1, and clang-tidy 23.1.1 under /usr/lib/llvm-23/bin
• MQT Core full-tree canary: ⬆️ Update clang-tidy to version 23 core#2328 (pending)
