Tekton Task e2e test rewrite

[gansheer]

Requirement

The existing tekton task e2e test needs to be rewritten.

From: https://github.com/apache/camel-k/pull/5505#discussion_r1602790606

Problem

The current test runs a kamel install ... command: https://github.com/apache/camel-k/blob/a09a41c6473f5fbf7970f8942841a1d31b043736/e2e/advanced/tekton_test.go#L45

Proposal

This does not really fit what the existing tekton task that actually executes a kamel run command.
