Feature: Support for setting folder alias names in the sidebar

### What feature or improvement do you think would benefit Files?

I'd like to request the ability to change the display name of pinned sidebar items (without changing the actual file name, like you could back in windows 7), and request a recent files sidebar widget for easier navigation

### Requirements

- This proposal will improve speed of accessing folders and organization

### Files Version

3.7.11.0

### Windows Version

10.0.19045.5073

### Comments

_No response_

No files, tests, or entry points are identified. First separate the folder-alias request from the recent-files sidebar widget request and locate the existing pinned-sidebar implementation; confirm which proposal is in scope before defining what completion means.
