search related track: remove quotes

[ronso0]

Simply removes noise from the menu.
If you think the search term doesn't stand out enough now, we could add an additional whitespace before the term:

Maybe there are also ways to change the font-weight or color.

The PR will conflict with #3213. Let's use this PR to collect opinions (before/after screenshots) and then directly implement the changes in #3213.

IMHO the field name and the value should differ more visible. Quotes are not optimal - what about using a fixed width font for the value? Or display the fieldname as the labels here in GitHub?

[uklotzde]

I find the text without the quotes hard to distinguish. Introducing QWidgetAction for custom styling requires more work.

For me it's hard to read with quotes :\

The example with 2 spaces works for me (3rd screenshot), but we can also look for strong unicode chars to separate the search term. Some inspiration (not all to be taken seriously):
Album Artist: "Roland Kaiser"
Album Artist „Roland Kaiser”
Album Artist: [ Roland Kaiser ]
Album Artist = Roland Kaiser
Album Artist ⊳ Roland Kaiser
Album Artist ☞ Roland Kaiser

The right triangle looks intuitive

The right triangle looks intuitive

there are more variants (lighter, heavier, other proportions) in case it looks to heavy when rendered bold/semi-bold in the menus.

@ronso0 This PR might be obsolete now with the latest additions and changes in #3213 (see screenshot)
