Optimize acceptance tests and E2E test - feed size

[davidgamez]

Description

As discussed here, further optimization of the acceptance tests can be performed by creating a separate GitHub action for large feeds. Currently, we have an exclusion list for large feeds that potentially break the CI due to memory consumption. In addition, their prolonged validation increased the billable time.

Proposed solution

• Create a separate GitHub action for large feeds.
• The list of large feeds will come from a list similar to this or can be retrieved using a similar approach proposed here
