Software - edit information - concept DOI validation

[dmijatovic]

On the software edit page we have place to input concept DOI. Some scrapers use this info to scrape citation information. The concept and versioned DOI's are usually provided by DataCite. We can validate if DOI is concept DOI and in case that it is version DOI we can extact the concept DOI using DataCite api.

The information about quering DataCite using GraphQL is provided in issue #289. This information can help build FE service to validate DOI and suggest concept DOI when version DOI is provided.

For the start we can add button "Validate DOI" below input. If not valid concept DOI we can use snackbar (warning type) and suggest concept DOI we find in version doi. Other design suggestions are welcome ;-)
