[doc] Adding the 'type' attribute description of <ButtonBase>

[chocolatl]

In HTML, the default value of the type attribute of the <button> tag is "submit", but in MDUI's <ButtonBase>, the default value of the type attribute is "button", which results in no form submission behavior by default.
This difference was confusing to me, although the type attribute of <ButtonBase> can be specified, but the doc did not give instructions, I hope to add a description of the type attribute in the document

@chocolatl Yes, I can confirm this point: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button.

I'm all 💯 with you on this pain point. There is room for improvement. We should improve the description:

@chocolatl Do you want to work on it?

@oliviertassinari I'm afraid not, My English is very bad 😓.

@oliviertassinari Can I fix this? Do we only want to add the prop's description in the doc? Or change the default value of it to submit as well?

@pnkapadia6 Of course, no need to ask :). The default value is expected. We need to make the behavior explicit in the API documentation page.
