Vscode-java-test: Improve the test result page

[jbelford]

The font size for the test result window is way larger than the editor. This should probably be fixed to scale the result window more appropriately so we don't need to zoom out.

There are a lot of issues related to the test report. I'll summarize here and work on a solution to improve it:

• [x] The report page is not responsive
• [ ] Cannot link to test item from the report (Tracked by #384 )
• [x] The color theme might be wrong when switching the theme of VS Code

There should be a link to open the method/class under test from the report

I find that the report view is also way too wide. Any messages just extend on the same line and require me to horizontally scroll. Some text wrapping would be nice, maybe even reducing the margins/padding. I think the report looks nice overall, but some simple improvements would really make an impact on how user friendly it is.

I find that after updating the color theme of VSCode, for example, from light to dark, the color of the opened test report will not be automatically updated unless you switch to another editor and switch back.

We did some refinement in #466 to the test report page. Those changes will be released in v0.12.0.

I'm closing this issue for now. If anyone still find there is anything needs to be improved. Please feel free to open a new issue.

Thanks.
