I have made `tools/setup/optimize-svg` do the SVG optimization
automatically rather than just telling you the command to run if they
need optimizing. This included adding a `--check` parameter to use in
CI to only check as we previously did rather than actually running the
optimization.
I have also made `tools/setup/optimize-svg` execute
`tools/setup/generate_integration_bots_avatars.py` once it has run the
optimization to ensure it is always ran.
This makes it one less command to run when creating an integration,
but also means that we catch instances where a PNG has just been
copied into the `static/images/integrations/bot_avatars` folder as the
only instance where this won't be run is if `optimize-svg` has not
been run which would be caught in CI.
Fixes#18183. Fixes#18184.
/bin/sh and /usr/bin/env are the only two binaries that NixOS provides
at a fixed path (outside a buildFHSUserEnv sandbox).
This discussion was split from #11004.
