Add Collection date to OSSF scorecard

[MoralCode]

This is a mostly-there first-pass at tackling #720. It adds the date to the bottom of the box for the OSSF scorecard and repo info tiles.

The ossf scorecard one works, the repo info is having some issues that ill work on (ignore my broken fonts on my machine)

TODO:

• [ ] Add the date format to the information popup on each tile
• [ ] detect the date format to use based on users browser locale settings (maybe)
• [ ] debug and fix the repo info tile date
• [ ] determine how to calculate the date for the repo info tile considering the data is coming from three different dataframes (should it just take the last date in the list? most recent? least recent? display a range of both?)

feedback welcome!

closes #720

Ok i think i fixed the repo info one too (mostly by ignoring 2/3 of the dataframes)

@MoralCode For repo_info it looks like its all coming from the same table, repo_info? If its more than one which ones are they?

[MoralCode]

Yeah, for now its just taking all the last updated data from repo_info. I think the releases data frame could be empty and the other one probably requires me to change another query.

I wanted to get an answer on how you want to handle/combine the three sets of values (see my PR comment) before doing all that
