Support repository urls ending with .git

[cmeessen]

Fixes #1244

Changes proposed in this pull request:

• scrapers recognise repository urls that end with .git and scrape them
• adds a sentence to the UI stating which URLs are supported
• update user documentation
• adds tests for the scrapers (disabled)
• rename GithubScaperTestIT to GithubScraperTestIT
• fix bug where scraping_disabled_reason text field shows number of characters of repository_url

How to test:

• docker compose down --volumes && docker compose build --parallel && docker compose up
  

• create four software entries with the following repository URLs (or those of you choice) and set them visible:
  • https://github.com/research-software-directory/RSD-as-a-service.git
  • https://github.com/research-software-directory/RSD-as-a-service
  • https://codebase.helmholtz.cloud/research-software-directory/RSD-as-a-service.git
  • https://codebase.helmholtz.cloud/research-software-directory/RSD-as-a-service
• wait for the scrapers to run or force them with:

  docker compose run scrapers /opt/java/openjdk/bin/java -cp /usr/myjava/scrapers.jar nl.esciencecenter.rsd.scraper.git.MainCommits
  

• verify that the software entries display the scraped information

PR Checklist:

• Increase version numbers in docker-compose.yml
• Link to a GitHub issue
• Update documentation
• Tests
