Cache being always missing

I’ve been struggling to find why the cache is always being missed.

Run lukka/run-vcpkg@v7
tool: C:\Program Files\Git\bin\git.exe
Fetching the Git commit id at 'D:\a\compress-tools-rs\compress-tools-rs\vcpkg' ...
0f0bd549dc2ac273bdb3dbd69b256815c09bcd0a
vcpkg identified at commitId='0f0bd549dc2ac273bdb3dbd69b256815c09bcd0a', adding it to the cache's key.
Cache's key = 'localGitId=707254936-args=1855044079-os=1553167250-imageVer=-2108626026-appendedKey=42-triplet=1258145250'.

I am not a big fan of sub-modules as I think this is an external dependency and could be fetched during the build process.

Another nice feature of using it dynamically is if you ever need to test different versions of libraries, and in this case, this can be done using a matrix project.

Check for vcpkgCommitId being a SHA1 hash added in run-vcpkg@v7.2, and improved docs as well.
