Add support for fixed version of project clones into the template

Add support for checking the latest version and warning if not on it to be added to the clone script

https://github.com/rdkcentral/hal-doxygen/blob/develop/template/docs/generate_docs.sh

Something akin to the same one for ut-core


# Clone the Unit Test Requirements
TEST_REPO=git@github.com:rdkcentral/ut-core.git

# This function checks if we're not sitting on the latest revision.
function check_next_revision()
{
    pushd ./ut-core 2&>/dev/null
    # Set default UT_PROJECT_VERSION to next revision
    if [ -v ${UT_PROJECT_VERSION} ]; then
        UT_PROJECT_VERSION=$(git tag | grep ${UT_PROJECT_MAJOR_VERSION} | sort -r | head -n1)
        UT_NEXT_VERSION=$(git tag | sort -r | head -n1)
        echo -e ${YELLOW}ut-core version selected:[${UT_PROJECT_VERSION}]${NC}
        if [ "${UT_NEXT_VERSION}" != "${UT_PROJECT_VERSION}" ]; then
            echo -e ${RED}--- New Version of ut-core released [${UT_NEXT_VERSION}] consider upgrading ---${NC}
        fi
    fi
    popd 2&>/dev/null
}

This sort of thing needs to be removed

# Set default UT_PROJECT_VERSION to master
if [ -z "${UT_PROJECT_VERSION}" ]; then
    UT_PROJECT_VERSION=master
fi
