Zenodo integration can't parse version for title

[gmyenni]

Zenodo is expecting "pure" semantic versioning (*.*.*, no v). It can't parse the dates we use as versions in the title, so all versions get titled "weecology/portalPredictions: None" (not sure why it's okay with dates everywhere else).

Options?

1. Using dates with the expected format (eg 2021.9.17) might work
2. Switch to actual proper versioning (bonus is that would allow more than one forecast a day, which could help with debugging)
3. Ignore it and hope it goes away

I like switching over to proper versioning, but I don't feel strongly about it.

If you change this (which I am totally fine with doing), we'll need to update the download_archive function here https://github.com/weecology/portalcasting/blob/main/R/download.R
