fix: ignore ts for panel type table

[nityanandagohain]

Since we don't have ts in table panel, it should not be there in expressions.

---

Important

Excludes ts from group tags in queries for table panel types in query_builder.go, with corresponding test updates in query_builder_test.go.

• Behavior:
  • In query_builder.go, expressionToQuery() now excludes ts from groupTags if PanelType is v3.PanelTypeTable.
• Tests:
  • Updated query_builder_test.go to reflect changes in expected queries for table panel types, ensuring ts is not included.

• Draft comment:
  The condition to exclude 'ts' from groupTags for table panel types is correct and aligns with the PR description.
• Reason this comment was not posted:
  Confidence changes required: 0%
  The change in the code ensures that the 'ts' field is not included in the group tags for table panel types. This is correctly reflected in the test cases, where the expected queries for table panel types no longer include 'ts'.

Can you help me understand what is the issue that necessitated removing ts?

[nityanandagohain]

@srikanthccv it's because of this #5908 (comment) . We have removed ts from panelTypeTable. Because of which expressions are failing in table panel types as it's trying to select timestamp from the subqueries and ts is not present in those subqueries.
