embedded public calendar on the website:

Describe the solution you'd like
a page, or part of a page, that contains an embedded version of the pubic facing calendar.

• Calendar should exist at /calendar or similar endpoint
• Should appear in the Software section of the About page

Describe alternatives you've considered
perhaps an in house mirroring of the public calendar, that seems overkill, however.

For this, we can just add an embed to a new static page, shouldn't be too difficult

[emilkovacev]

The steps should be as follows:

1. Create a new static page under templates > calendar > index.html
2. Add the iframe embed to the html
3. Update urls.py to reflect new /calendar path
4. Add the link to the calendar on navbar (replace Announcements maybe?)
