Scrypto coverage, llvm no recognized

[a137x]

scrypto coverage command produces error, not recognizing installed llvm of proper version.

❯ scrypto coverage
Missing command: llvm-cov-17. Please install LLVM version matching rustc LLVM version, which is 17.
For more information, check https://apt.llvm.org/
Error: CoverageError(MissingLLVM)

test environment:
Apple Silicon, MacOS 14.2.1, llvm installed via homebrew

❯ llvm-config --version
17.0.6

❯ scrypto -V
scrypto 1.1.0

❯ rustup -V
rustup 1.26.0 (2023-04-05)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.74.1 (a28077b28 2023-12-04)`

Apparently the culprit lies in spelling of llvm-cov command (at least to my specified OS)

Next week I'll add PR with the fix, it will check version of llvm before trying llvm-17.
