Missing formula for maven 3.6.3

`brew gist-logs <formula>` link OR `brew config` AND `brew doctor` output

#brew gist-logs maven@3.6
Error: No available formula with the name "maven@3.6"

[X] I ran brew update and am still able to reproduce my issue.
[X] I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

After a brew update, maven version bump to 3.8.1, the lates stable release, but company constrains, for now, doesn´t allow to use maven versions higher that 3.6.3. Trying to make a version downgrade wasn´t possible, since there is not such formula.
