build: standardize apt-get usage, remove blackfire from apt sources, for #6235, for #6078

[stasadev]

The Issue

• Upgrade failing due to Blackfire "payment required" error #6235

apt-get update can fail in the user's custom Dockerfiles.

I thought we could search for apt-get update using a regex and automatically replace it in the resulting Dockerfile, but that seems like overkill because people can write it with different variations, like:

• apt-get update
• apt-get update -y
• apt-get update -qq
• apt-get update -qq >/dev/null

And the same with apt, so it's probably impossible to write a good regex to cover all cases and not break anything.

How This PR Solves The Issue

Replaces apt-get update with (apt-get update || true) in the docs.

Uses apt-get instead of apt everywhere.

Removes /etc/apt/sources.list.d/blackfire.list as we pin the blackfire package to a specific version and don't need it in apt-get update:

• blackfire upgrade is failing, needs to be fixed #6078

Manual Testing Instructions

1. ddev start
2. ddev ssh
3. sudo apt-get update | grep blackfire should give an empty result

Release/Deployment Notes

IMO we should remove the /etc/apt/sources.list.d/blackfire.list after the installation in the ddev-webserver Dockerfile, since Blackfire is such low priority and since it so often causes trouble. That can be done here or in a later PR.

Thanks for this! Let's just use apt-get update and apt-get install and apt-get upgrade` in all the places, just for consistency. It also prevents the "no consistent api" message or whatever it is.

Thanks, looks perfect.
