[ci] disable fail fast behaviour for ci workflows

[mahadzaryab1]

Which problem is this PR solving?

• Resolves Do not fail all CI matrix jobs if one of them fails #6051

Description of the changes

• Added the fail-fast flag to all workflow files that use a matrix strategy to avoid other jobs from aborting due to a single job failing (read more about the fail-fast flag here).

How was this change tested?

Introduced a failure in the Cassandra E2E Test. This test failed fast and prevented other workflows in the matrix from running.

After adding fail-fast: false to the workflow file, the other tests were still able to complete.
