No default port is bound, so hard to use on gitpod or codespaces

[RCheesley]

Hi folks!

When we tried to upgrade to 1.22.0 in this PR we came up against an issue whereby the PHPMyAdmin port was not getting correctly kicked off in Gitpod, so it was not accessible to users for testing.

It might well be a problem that other Gitpod / Codespace users come across, and can be worked around with the docker-compose.gitpod.yml using

services:
  phpmyadmin:
    ports:
    - "8036:80"

in case others come across this from search (thanks @rfay for the suggestion!) but it might be helpful to declare the ports explicitly in the plugin?

I think this should be pretty easy to deal with. What we can do is

if the router is not enabled (Detect maybe with {{ .DdevGlobalConfig.omit_containers}} )

• Add a docker-compose.phpmyadmin-norouter.yaml with the contents above
• Add to removal_actions the deletion of that file (see https://ddev.readthedocs.io/en/latest/users/extend/additional-services/#sections-and-features-of-ddev-get-add-on-installyaml)

That should do it. PR is welcome.

Please test

• fix: directly expose port on 8036 when router disabled, fixes #3 #4

Testing instructions are there. I think it should sort this out, seems to work OK for me on gitpod.
