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

[sarutak]

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.

@sarutak sorry for the late reply. It seems that the test is ignored. Shall we enable it in this PR?

[sarutak]

@gengliangwang Thank you for the reply. The reason the test was ignored seems flakiness (#6345).
But it's 6 years ago and now it's difficult to know how flaky the test was.
How about enabling the ignored test and disable again if it's still flaky?

[gengliangwang]

If we are not going to enable it, it doesn't make sense to fix it...
Let's see how the CI test behaves. I tried on my local setup and the test passes.
