…ute_capability related errors (sonic-net#766)

#### How did you do it?
Added 2 regex to loganalyzer_common_ignore.txt file to ignore
1. sai_query_attribute_enum_values_capability "rv=-8", ignoring
   non-functional error in swss PR pipeline till
sonic-net/sonic-swss#3866 is merged
2. sai_query_attribute_capability "error -2", ignoring till it gets
   fixed from SAI, CS00012422823 is raised

Summary:
Fix flaky PgMinThreshold test by correcting drop count comparison logic
and packet handling sequence.
The PgMinThreshold test validates buffer behavior between two priority
groups:
- PG0: No minimum threshold (uses shared pool only)  
- PG1: Has minimum threshold configured
The test was failing intermittently due to incorrect drop counter logic
and simultaneous packet transmission causing race conditions.
Fixes # (issue)

### Approach
#### What is the motivation for this PR?
The PgMinThreshold test was flaky, causing CI failures. The test needs
to reliably validate that:
1. PG without minimum threshold drops more packets when shared pool is
exhausted
2. PG with minimum threshold gets guaranteed bandwidth allocation
#### How did you do it?
1. Fixed packet sequence: Send packets sequentially instead of
simultaneously
2. Corrected drop logic: Enable queue to free up queued packets so
shared pool can be fully utilized.
3. Added PG min configuration: Ensure PG minimum size is properly
updated
4. Fixed assertions: Compare that PG without threshold has significantly
more drops

#### How did you verify/test it?
Validated the changes on TH5 platform where the test now executes
reliably with consistent results as expected.

#### Any platform specific information?

#### Supported testbed topology if it's a new test case?
