Work on the Translations Dashboard

[hturner]

Reviewing the open issues for the translations dashboard:

• move table codes away from index.Rmd translations-dashboard#8 - seems a matter of taste, low priority
• Try not to depend on stringr translations-dashboard#9 - possibly useful, but GitHub actions have been running fine
• analyze and visualize translations metadata translations-dashboard#11 - could be something to follow up, I added a comment there
• Add timeline for translation events translations-dashboard#12 - may be nice to have, but could be hard to maintain.

There are other issues that could be discussed and possibly some initial work could be done:

• How to better integrate the Weblate and SVN Dashboards
• Adding text to explain the difference between the dashboards (the main one shows the status in the source code for R-devel, which will only change when an R Core member commits a patch - maybe once a quarter, whereas the Weblate one shows the status on Weblate, which can change continuously)
• Showing activity over time on Weblate, to show general activity and bursts corresponding to translatathons, dev days etc

If these or other improvements are discussed/worked on, it would be good to open a corresponding issue on the dashboard repo: https://github.com/r-devel/translations-dashboard/issues
