chore: unskip mssql tests (appsmithorg#36866)

## Description
This PR fixes the flaky mssql Junit test case by replacing the test
containers docker image to mssql server 2022 latest.

### Root cause of flakiness
MSSQL Junit test cases like `mssqlplugintest.java` and
`mssqlGetDBSchemaTest.java` recently started becoming flaky in the CI.
Sometimes they would pass, sometimes they would throw the error
`org.testcontainers.containers.ContainerLaunchException: Container
startup failed for image mcr.microsoft.com/azure-sql-edge:1.0.3`. This
was happening because MSSQL test cases create a docker container using
Azure SQL Edge 1.0.3 image. Upon further researching found two relevant
links as to why it has stopped working:
1.
https://forums.docker.com/t/sql-server-docker-container-fails-on-start-up-when-run-in-a-vm-with-ubuntu-24-04/142093
2. docker/for-mac#7368

Although second link seems to be specific for Mac where as we use Ubuntu
when running tests in CI, this
[comment](docker/for-mac#7368 (comment))
and docker forum link above states that problem is there for Ubuntu as
well. Two possible workaround suggested in above threads were:
1. Downgrade docker desktop to 4.32 
2. Instead of Azure SQL Edge use MSSQL server 2022 latest image

This PR uses the second workaround and updates docker container image
from Azure SQL Edge 1.0.3 to MSSQL server 2022 latest image.

I have triggered the server-unit-tests workflow 12 times and all times
it passed, showing no flakiness, hence we should be good to go ahead
with the fix.
