tech-database: mongodb about.md

[CorruptComputer]

The instructions on this page are wrong: https://developer.fedoraproject.org/tech/database/mongodb/about.html

On default Fedora 35 installation the following errors are shown when trying to install this with the shown commands:

[username@hostname ~]$ sudo dnf install mongodb mongodb-server
Last metadata expiration check: 2:57:12 ago on Fri 22 Apr 2022 04:26:06 PM EDT.
No match for argument: mongodb
No match for argument: mongodb-server
Error: Unable to find a match: mongodb mongodb-server

Unfortunately, this is a known issue: #346

I am not sure if we should remove the page completely considering that MongoDB was removed due to the new licensing or point it to upstream documentation on this.

Will be fixed by #456

Can I be assigned this issue?

[jackorp]

Should be fixed by now and for now.
