fix: Replace some more icons with outlined ones

[kra-mo]

Follow-up to #54054

For the folder icons, I suppose we should have been clearer that retaining the filled variant only applies to the main view, not menus, sidebars, etc.

LGTM :)

We detected that the Electron Renderer process just crashed.

We have failed the current spec but will continue running the next spec.

This can happen for a number of different reasons.

If you're running lots of tests on a memory intense application.

• Try increasing the CPU/memory on the machine you're running on.
• Try enabling experimentalMemoryManagement in your config file.
• Try lowering numTestsKeptInMemory in your config file during 'cypress open'.

I'm guessing this is not my fault by increasing the memory footprint of the SVG 1000x or something? :D
