Increase timeout for VPA v1 e2e tests

With switch to ginkgo v2 timeout are counted differently[1]. With Ginkgo v1
timeout was per-test-suite. Now its for the whole test run. As a result
`actuation` [2] tests for `v1` API are timing out. They take a little more than
60 minutes. For example passing run [3] logs first '[v1]' at 19:30:23.701
and the last one at 20:33:44.510.
