Remove repositories that are not participating in Hacktoberfest 2021 from the list.

[OtacilioN]

This is a really good task for beginners, you can help with this awesome list by checking the repositories list.

If you find a repository that:

• Is not available anymore
• Is not being maintained anymore (11+ months of inactivity)
• Is not accepting pull requests anymore for hacktoberfest 2021
• Pull requests are not counting for hacktoberfest
• Repositories that are "only to add your name" or something that's clearly an attempt to simply +1 your pull request count for October.

For hacktoberfest 2021 maintainers have to opt-in their repositories to the event to make pull request count

Maintainers can do it in two ways:

• By adding the topic hacktoberfest to their repository
• Or by adding the label hacktoberfest-accepted to pull requests.

You can make a pull request removing one or more of these repositories.
