Increase hit area for file multi-selection checkboxes

[martinhoT]

Summary

Default checkboxes are now wrapped by a padded label, as indicated in the screenshot below (purple is clickable).

Test Plan

Try to click slightly outside the checkbox at the left of a file entry in the file manager. Multi-selection should still work (i.e. previous file selection is not forgotten). Check the size of the label with Dev tools, and verify that the size is appropriate.

Verify the above in the list and grid views.

@joselfrias do you know how are we doing release cycle of this component?

[joselfrias]

Yes.

The way i've been doing is (sorry, I don't have the commands at hand now :/ ) :

1. Increase the version in this frontend\package.json and run the npm commands to build the new version of the package. At first I tend to create a version like 4.1.1.beta.1 and only when it is approved in other components (we must issue as well a PR that updates the package version in that), I push to GH packages the 4.1.1 version (and issue a new PR in other components to update).
2. Publish to GH packages (check the token for github, it needs to contain packages permissions).

In this PR or the other (I intend to approve both at the same time) can we bump the version at version.txt? Maybe 1.3.1
