fix: update default branch

[ohemelaar]

Discourse now uses main as the default branch. Switching from master to main allows updating discourse to newer versions

Newer versions may require fixing permissions on redis' files

hi. thanks for the PR and apologies for the belated response.

unfortunately the tests are failing, and i can't debug the tests as i can't create X86_64 vm on my local machine, so i can't verify the change.

are you able to understand why the build is failing? (it might be helpful to view "Raw logs"). it's failing on this test:

dokku-discourse/tests/suite.bats

Lines 5 to 12 in c5ef604

	@test "should create a new discourse app" {
	echo "127.0.0.1 $HOSTNAME" | sudo tee -a /etc/hosts
	dokku discourse:create "$APP_NAME" "$HOSTNAME" "$DEVELOPER_EMAILS" "$SMTP_ADDRESS" "$SMTP_PORT" "$SMTP_USER_NAME" "$SMTP_PASSWORD"
	grep -qxF "$(dokku apps:list 2> /dev/null)" <<< "$APP_NAME"
	# Is discourse actually running?
	curl "$HOSTNAME" 2>&1 | grep -q "Discourse Setup"
	}
