[UT] Remove potentially buggy SQL test case for mem_pool property of resource groups

[arin-mirza]

Why I'm doing:

I recently added E2E SQL test cases for testing the mem_pool property.

• [UT] Add SQL tests for mem_pool property of resource groups #65859

One of the test cases has an incorrect regex.

show verbose resource groups all;
-- result:
[REGEX][^shared_resource_group_for_brad]
-- !result

The intention was to assert that the expression cannot be matched in the result.
It instead tries to match a single character that is not present in the brackets.
The correct regex should use a negative lookahead to implement the intended behavior.

The test case, however, does not fail, as the result coincidentally does not start with any of these characters.

What I'm doing:

The check is actually redundant, as we already assert that the resource group was not created in the previous check.
Instead of adding another complicated regex with negative lookaheads, I am simply removing it.

Note

Removes an incorrect regex-based assertion and a duplicate show verbose resource groups all call from the mem_pool resource group test.

• Tests (SQL mem_pool resource groups):
  • Remove invalid regex assertion block from R/test_create_two_resource_groups_with_mem_pool_different_mem_limit that attempted to verify absence in show verbose resource groups all output.
  • Simplify T/test_create_two_resource_groups_with_mem_pool_different_mem_limit by removing a duplicate show verbose resource groups all call, leaving a single invocation.

The failing test case seems to be unrelated to my changes.

Bug: T file not updated to match R file changes

The R (result) file had a show verbose resource groups all; command and its result block removed, but the corresponding T (template) file at test/sql/test_resource_group_mem_pool/T/test_create_two_resource_groups_with_mem_pool_different_mem_limit still contains two show verbose resource groups all; commands at lines 22-23. This creates a mismatch where the T file expects two executions of this command but the R file only defines expected results for one, which will likely cause test failures or incorrect test behavior.
