[Enh]: Conflict dialog improvements

[marcoambrosini]

(suggestions from @peter in the design feedback conversation)

Team, I would suggest some improvements for this popup, as for me it is not so immediate which checkbox to select.
Things I would do to start improving it are:

1. To emphasize more the question "Which files do you want to keep?" instead of the path which is not so relevant.
   2.Once the new file is selected, change the button label to "Overwrite" or "replace".

Looping @tobiasKaminsky since the mobile version is similar.

Additional points:

• We could also put the "If you select ... be overwritten." text into an info callout component.
• Title of the dialog could be "[n] file conflicts, which files do you want to keep?"
• The path could be in a simple p element just above the callout
