[SPARK-36512][UI][TESTS] Fix UISeleniumSuite in sql/hive-thriftserver

### What changes were proposed in this pull request?

This PR fixes an issue that `UISeleniumSuite` in `sql/hive-thriftserver` doesn't work even though the ignored test is enabled due to the following two reasons.

(1) The suite waits for thriftserver starting up by reading a startup message from stdin but the expected message is never read.
(2) The URL and CSS selector for test are wrong.

To resolve (1), this PR adopt the way that `HiveThriftServer2Suite` does.
https://github.com/apache/spark/blob/3f8ec0dae4ddfd7ee55370dad5d44d03a9f10387/sql/hive-thriftserver/src/test/scala/org/apache/spark/sql/hive/thriftserver/HiveThriftServer2Suites.scala#L1222-L1248

This PR also enables the ignored test. Let's disable it again in the following PR if it's still flaky.

### Why are the changes needed?

Bug fix.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

CIs.

Closes apache#33741 from sarutak/fix-thrift-uiseleniumsuite.
