A script to automatically update forgejo installed on local host to the latest release.
Place in an appropriate location on local host and execute on schedule via cron.
Requires some basic shell commands listed in the script, and assumes that
systemd is used to start/stop forgejo.
Assumes that forgejo is executed from a symlink specified in $DIR. The actual forgejo binaries are placed in $DIR/bin. This script will automatically update the symlink when a new verson is downloaded.
