[Tests-Only] Fixup API sharing test suite names

[phil-davis]

Description

In PR #37938 I standardized references to sharing API test suites for sharing to the root folder and sharing to the Shares folder.
But I didn't actually rename the folders in tests/acceptance/features/apiShare*
CI passed - e.g. https://drone.owncloud.com/owncloud/core/27018/60/13

Running apiShareCreateSpecialToRoot1 tests tagged ~@skipWhenTestingRemoteSystems&&~@skipOnOcV10&&~@skipOnOcV10.6&&~@skipOnOcV10.6.0&&@api&&~@skip 
No scenarios
No steps
0m0.26s (13.93Mb)
Information: no matching scenarios were found.
runsh: Total 0 scenarios (0 passed, 0 failed)
runsh: Exit code of main run: 0

Which is a bit sad - when the folder for the suite does not even exist, it happily decides that there are no feature files, no scenarios and that's it.

Fix this - get the suite names all in sync between .drone.star behat.yml and the actual folder names.
