Adjust default Chosen width

[joshuasosa]

Problem/Motivation

After implementing #3966, the default Chosen width may appear too narrow.

Describe the bug

In some cases, the default width is too narrow for the dropdown select box enhanced with Chosen.

To Reproduce

Steps to reproduce the behavior:

1. Go to Content > Add content > create Page.
2. Click on "Menu settings" section and checkmark "Provide a menu link."
3. Click open "Parent link" and observe Chosen's width is narrow.
4. Compare with an existing Page that is in the menu.

Proposed resolution

Options to fix:
A. An issue and patch could be created for Chosen to change width to min-width in the CSS.
B. Minimum width could be set to a relative percentage (e.g., 30 with "Use relative width" enabled).
C. Minimum width could be unset and left blank, where width: auto will then get applied.
Or some combination of fixes.

Comment by @bberndt-uaz:

From some quick testing locally, I think we could leave that Chosen "Minimum width of widget" option blank (so the container would be set to width: auto) and then we could also override the .chosen-drop class to have width: max-content. That seemed to provide a good solution, although there might be a better one.

Expected behavior

Width of Chosen-based dropdown should adjust based on the content within the dropdown.
