[FIX] microsoft_calendar: Send html description to outlook

Step to reproduce:
- Create a with a link in the decription
- Edit + Save multiple times

Current behaviour :
- Since c2b545f we fetch the full
description with html tags which are rendered via the
- When we resend this message to outlook, the description
 will be updated via html2plaintext.
 In the case of URL, they will be added as a footnote and thus
 duplicated if the url is it's own name

Behaviour after thr PR:
- We could then also send the description with the html tags to
ensure full compatibility between the description
- Using html2plaintext update the descrtiption to markdown, with some
issues, since html is now supported in the odoo editor, using
html on both end will remove the need to use html2plaintext and
the descriptions changes stemming from it.
