Missing libs in most recent image

[maxcountryman]

I've recently started seeing the following errors with the latest image:

@maxcountryman could you specify the command you're running the image with?

[maxcountryman]

@tyranron docker run -it -p 4444:4444 instrumentisto/geckodriver

@maxcountryman anything else to reproduce the issue? I have the following:

$ docker run --rm -it -p 4444:4444 docker.io/instrumentisto/geckodriver:126.0-driver0.34.0-r0

@maxcountryman ok, I was able to reproduce the issue. Strangely, despite the errors written into logs they don't affect any use cases of our WebDriver usage and all our builds/tests are OK.

[tyranron]

@maxcountryman we install all the dependencies of firefox-esr Debian package, since Debian doesn't have a package for non-ESR Firefox, and as the versions of ESR and non-ESR may differ quite much, such problems may happen.

I've added these libs, so try out the 126.0.1-driver0.34.0-r1 image version. I've tested it in our pipelines and the error has gone.

The worst part, I don't know how to build a test to catch such regressions in the future. If you have any ideas in mind, PR is welcome.

Thanks for this. I'll give it a try shortly.
