Convert underscore to hyphens in generic attributes names

[yakky]

Just a draft idea to address #267 to see if there is any interesting in solving the issue

The change replace _ to - in generic tag attributes

So i can do something like {% bootstrap_button data_bs_toggle="collapse" data_bs_target="#update-group-9" button_type="reset" content="Cancel" %}

Generic attributes (like data_bs_toggle) are passed to render_tag without any changes while templatetag arguments (like button_type) are not, so it's safe to make this change without interfering django-bootstrap5 behaviour

Yes, please merge these changes.

@dyve is this something you'd be interested to merge? If so I will complete this with tests to make it actually mergeable

The idea of converting data_ tot data- is interesting. For anything not starting with data_, it becomes a possible risk I think.

the idea behind this PR is to allow integrating htmx attributes (hx-*) which is currently not possible to support

Ok, Let's see it.

@dyve this is a first draft. I included tests to check that no existing attribute is altered
