Update to work with most recent version 3.0.0

[roele]

It seems the repository was not updated for a while and the scripts do not work with most recent version (and on a Mac M1). The files should be updated to work with recently released version 3.0.0 and Mac M1 ARM architecture.

@roele Does this container set-up work for 3.0 yet?
Does it even need to be updated in the first place? Was it tested?

@Aquaengraved Yes it works, I used it to test an upgrade from 2.8.4 to 3.0.1 on my ARM M1 Mac, hence the mysql:8.0.28-oracle version. An update is required in regards of PHP version and if you want to run it on a M1 Mac (only Oracle seems to provide an ARM image).

hello, I created a pull request #27 with latest modx 3.0.5.
I've tested it and it works 😄 .

Can you have a look at it?
