Rename job trace to job log in webIDE component

What does this MR do and why?

A tiny MVC for: #341163 (closed) to rename the internal logic from trace to job log. A follow-up merge for the build-trace CSS class should be opened to handle this in conjunction with the projects jobs page.

Known issues:

• We still maintain build-trace as a CSS class given it is shared between general Jobs and the IDE inside the build.scss file.
