Convert Test_org_eclipse_swt_custom_BidiSegmentListener to use assertThrows instead of try-catch blocks

[Copilot]

• Add assertThrows import from JUnit Jupiter
• Convert testListener method to use assertThrows instead of try-catch when exception is expected
• Convert testStyleRangeSegmenting method to remove unnecessary exception handling
• Simplify assertThrows usage - cleanup code now outside assertThrows lambda
• Ensure listener is always removed by placing cleanup in finally block
• Verify the changes compile and tests pass

Original prompt

Convert Test_org_eclipse_swt_custom_BidiSegmentListener.java to use assertThrows instead of custom try-catch blocks

@copilot also look at preliminary work for a similar example by @akurtakov here #2579

Simplified the assertThrows usage following the pattern from PR #2579. The cleanup code is now outside the assertThrows lambda, making it cleaner and more straightforward (commit 582b0ab).

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/eclipse-platform/eclipse.platform.swt/pulls/2579
  • Triggering command: curl -s -H Accept: application/vnd.github.v3+json REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Ensure text.removeBidiSegmentListener is always called by putting it in finally block

@copilot please consider the remark from @akurtakov here #2580 (comment)

Applied the suggestion - the listener cleanup is now in a finally block (commit 0bb8226).

@copilot Ensure text.removeBidiSegmentListener is always called by putting it in finally block

Wrapped the test code in try-finally to ensure the listener is always removed, even if an exception or assertion failure occurs (commit 0bb8226).
