E2E tests: Research Brute Force tests failures

[mauromalara]

Description

After the debugging and testing achieved in #3166, we could see that the tests in test_brute_force were failing, so we must find the reason for the failure and a solution for it.

The RDP failure seems to be produced by the hydra version because it just fails in @BelenValdivia environment. Her error message has passwords in plural, while we expect password. We should install a specific hydra version.

My current hydra version is:

hydra -v
Hydra v9.2 (c) 2021 by van Hauser/THC & David Maciejak - Please do not use in military or secret service organizations, or for illegal purposes (this is non-binding, these *** ignore laws and ethics anyway).

[BelenValdivia]

I executed the rdp test with Hydra v9.0. My localhost is a Ubuntu 20.04

[BelenValdivia]

I upgraded to Ubuntu 22.04 and Hydra v9.2 and the test passed

I fixed the test_brute_force_rdp test by specifying the version of Hydra to be installed (v9.2).

Also, I added a role to search for the alert before fetching the alerts.json.

Results	Note
🟢 (6 rounds)	In R2 and R6 RDP fails, so I fixed the error by removing the failed_when condition because it's unnecessary (the command is executed but ansible does not wait for it to finish)
🟢	6 rounds of RDP only to check the change mentioned in the previous note.
