minirst: dynamically compile admonitions regexp

Currently, parsing admonitions uses a static regular expression created
from a pre-defined list of admonitions. A future patch will introduce a
feature that needs to parse custom admonitions. Prepare for this by
compiling the admonitions regular expression during each function
invocation.

Strictly speaking, there is a slight performance loss here. But we only
run this code as part of displaying help text. I don't think the loss
will be noticeable and I don't think we care if it were.
