needs update

I am using this via the docker container https://hub.docker.com/r/martinjohn/nagios

just hit this problem whereby the script nolonger works
https://unix.stackexchange.com/questions/644442/speedtest-cli-valueerror-invalid-literal-for-int-with-base-10

so I did the wget of speedtest.py to /opt/Custom-Nagios-Plugins
and also had to modify STb in check_speedtest-cli.sh
and copy in the file speedtest

would be nice if someone could update the docker container
