Don't try to install --force when passed to bootstrap

[Eeems]

Describe the issue
Bootstrap tries to install --force when the flag is passed to it.

To Reproduce
Steps to reproduce the behaviour:

1. run bootstrap --force
2. It will complain about --force being ambiguous and that there is no package selected to install.

Expected behaviour
--force should not be passed to the extra packages to install.

Screenshots
N/A

System information:
toltecctl status output: N/A

Additional context
Install works as expected still, there is just some noise in the output. This was found when running rM-docker.

For anybody finding this. The --force flag is not intended to be used by anybody but maintainers for testing toltec on new OS versions. It is not supported, do not use it, and do not include it in guides.
