Although very common, bash is not guaranteed to be located at
`/bin/bash`. NixOS is an example of this.
More commonly, `/bin/bash` can be quite out of date. An example of this
is MacOS's version of `bash`. This realistically won't affect Playwright
but it's worth noting. You can technically update MacOS's system version
of bash but you need elevated permissions to do so.
By using `/usr/bin/env bash` instead of `/bin/bash` we can execute
Playwright's bash scripts in like NixOS and generally improve the
selection behaviour for bash in other systems too.
Some discussion of why it's worth favouring `/usr/bin/env bash` over
`/bin/bash`:
- Discusses `/bin/bash` missing in NixOS:

- Some general commentary on why `/usr/bin/env bash` is favoured:

Improves situation at #5501
This removes everything related to docker integration experiments that
we conducted over the last 6 months.
I'll send a follow-up with an alternative suggestion that was demo'ed on
a team meeting in the end of December.
This patch:
- adds a new `Dockerfile.vrt` image file based on focal that installs
VRT-related dependencies inside it.
- updates scripts to build & publish the new docker image.
Drive-by: remove stale file
