ActionList v1 and v2: Use icon instead of input for multiple selection

[siddharthkp]

Part of https://github.com/github/primer/issues/447
Fixes half of https://github.com/github/primer/issues/228

Nested interactive controls are not announced by screen readers, the accessibility advice here is not use interactive elements for presentation.

• Replace readonly input type="checkbox" with svg from primer/css
• Bonus: checkmark consistency across browsers :)

Future - The svg used here has a short life and will get replaced with the Checklist component when it's ready

The solution is so interesting! I've never heard of someone using an svg instead of a checkbox for a11y reasons. Why not use the solution proposed in https://github.com/github/primer/issues/228 where they recommended to make the role presentational ? Is that for checkbox browser consistency?

We are? 😅 The example mentioned in the issue uses an image with role="presentation":

<lirole="menuitemcheckbox" aria-checked="true"><imgsrc="checked.gif" role="presentation" alt="">
Sort by Last Modified
</li>

From what I understand, having an interactive element inside a selectable listbox option or menuitem isn't valid. See violations on story

Exactly. input needs to be in a form and ActionList isn't really a form scenario. I attended a popup a11y meeting last week and was able to confirm this with a screen reader user, which was super helpful!

LGTM, and it doesn't break the multiselect behavior in Autocomplete 🙌
