gh-38049: Fix broken docker/Dockerfile

<!-- ^ Please provide a concise and informative title. -->
<!-- ^ Don't put issue numbers in the title, do this in the PR
description below. -->
<!-- ^ For example, instead of "Fixes #12345" use "Introduce new method
to calculate 1 + 2". -->
<!-- v Describe your changes below in detail. -->
<!-- v Why is this change required? What problem does it solve? -->
<!-- v If this PR resolves an open issue, please link to it here. For
example, "Fixes #12345". -->

As mentioned in
#37856 (comment) the
`Dockerfile`  is broken by #37856.
This will be fixed in this PR.

More precisely we replace `install_scripts` by appending
`$SAGE_ROOT/local/bin` to the `bash` path variable. This does not affect
Sage but ensures easy access to `gap`,  `maxima`, ... in a `bash`
session (see
#37856 (comment) ff).
