Matrix Promotion to Beta

Matrix was introduced in Tekton Pipelines 0.38. We have introduced a lot of testing around matrix feature including unit/e2e/integration tests. Matrix unblocks variety of use cases for systems migrating from travis/jenkins. This is a very crucial feature for many end-users while allowing to maintain clean, concise, and flexible catalog of pipelines. Part of #5265 and #6110 Signed-off-by: Priti Desai <[email protected]>
