This PR modifies the init Action to add a go wrapper script to the PATH if we are running on Linux in order to better cope with tracing builds for Go 1.21 and above. This works as follows:

• If we are initialising CodeQL for Go and we are running on Linux, then we obtain the current path to the go binary.
• We query the type of executable with the file command.
• If this contains the string "statically linked", we install the wrapper script to a bin directory in the CodeQL temporary directory.
• We add that bin directory to the system PATH
• We store the location of the wrapper script in a new environment variable, CODEQL_ACTION_GO_BINARY (we could probably omit this since the path can be reconstructed in the analyze step)

Additionally, we verify that the result of which go points to our wrapper script in the analyze step by checking it against the value of CODEQL_ACTION_GO_BINARY to make sure that users did not e.g. use a setup-go step after the init action.
