This is a tool for upgrading status-go to a given version in:
${VERSION_FILE}
Which is then used by Nix derivations to build status-go for the app.
If the given name matches both a branch and a tag the tag is used.

Usage:
    ${SCRIPT_FILE} {version}

Examples:

    # Using branch name
    ${SCRIPT_FILE} feature-abc-xyz

    # Using tag name
    ${SCRIPT_FILE} v2.1.1

    # Using PR number
    ${SCRIPT_FILE} PR-2134
