Cypress: Retry mechanism for e2e tests

[FedeAlonso]

https://issues.redhat.com/browse/RHOAIENG-16485

Description

Add a retry mechanism to the e2e Cypress tests.

How Has This Been Tested?

I've forced the failure of the application.cy.ts test here 9a1c676
Then I've ran the cypress job (cypress/job/cypress-tests/59)
In the report, 3 attempts are shown:

Then I've fixed the test here 8e55ff2
And ran the cypress job (cypress/job/cypress-tests/60)
And the test was up and running fine again

Test Impact

It's an "enhancement"

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit or cypress tests for related changes)

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main
