[ENHANCEMENT] Arrange the logic of working with bootstrap

[click0]

Is your feature request related to a problem? Please describe.
In the script usr/local/share/bastille/bootstrap.sh
only one argument $1 is used, through which the FreeBSD|HardenedBSD|MidnightBSD system version, template url and different versions of Linux builds are passed.
My choice of FreeBSD 12.3-STABLE(-LAST) is used for HardenedBSD.

Describe the solution you'd like
I want to increase the number of arguments to 2 and use a similar syntax:

bastille bootstrap FreeBSD 12.0-RELEASE
bastille bootstrap FreeBSD 12.3-STABLE
bastille bootstrap HardenedBSD 12.1-releng
bastille bootstrap template https://gitlab.com/BastilleBSD-Templates/syslog-ng
bastille bootstrap Linux debian-bullseye

Describe alternatives you've considered

Is there a reason you want this? Or use case?

Thanks!
