Investigate asset file fingerprinting

[eric-schneider]

When we temporarily pulled the global nav after launching the unified site on new AWS infrastructure, some users experienced UI issues like the top part of the page being cut off:

@mlr thinks this is likely the browser caching old styles, and that the usual way to mitigate this is asset file fingerprinting. However, we're not sure if that’s something Antora supports out of the box. We should investigate if asset file fingerprinting is a desirable and achievable solution to this problem, since we will be adding more rich UI experiences in the near future.

A cursory search didn’t turn up any existing support for this from Antora unless they name it something else. It would most likely require a custom plugin/extension.

@mlr Do expect this to be an extension for the UI or Antora itself? Or both?

[mlr]

@eric-schneider not sure, it may not be doable without modifying Antora internals. Hard to say for sure without further exploration
