[Devtools] Removed timeline setting from network log settings

This patch ensures there are no lingering "timeline" setting for network
log settings. "timeline" or "waterfall" may have been saved into the
users settings and when the new waterfall came out it may have caused
some users to see "timeline" as a custom column; this removes that.

[Automated comment] Request affecting a post-stable build (M55), manual review required.

 Issue 672096  has been merged into this issue.

Is this change applicable to all OSs or any specific os?

Sorry, I didn't realize we where rolling out. Requesting 56 instead.

Approved for M56 branch 2924.  Marking as OS-All given that DevTools are applicable cross-platform, but correct me if this wouldn't show up on certain platforms e.g. Android.

Looks like the promotion of the dev channel took the change into beta, so no need for a merge any more.

Thanks!

Nope, it didn't make it into M56 (Beta).

Your change meets the bar and is auto-approved for M56. Please go ahead and merge the CL manually. Please contact milestone owner if you have questions.
