Ignore source map files by default

[djfpaagman]

Source maps are becoming more popular. Rails 7 is moving towards replacing Webpacker with other tools, for example jsbundling-rails. This gem puts build files in the app/assets/builds directory:

This gem provides installers to get you going with the bundler of your choice in a new Rails application, and a convention to use app/assets/builds to hold your bundled output as artifacts that are not checked into source control

If you use jsbundling-rails and enable source maps they are picked up by i18n-tasks, for example:

❯ i18n-tasks missing
Missing translations (2) | i18n-tasks v0.9.35
+--------+-----+-------------------------------------------------+
| Locale | Key | Value in other locales or source |
+--------+-----+-------------------------------------------------+
| all | !0 | app/assets/builds/application.js.map:4 (1 more) |
| all | !1 | app/assets/builds/application.js.map:4 (2 more) |
+--------+-----+-------------------------------------------------+

I think it makes sense to ignore these by default, so I've simply added the extension to the exclude list.

Let me know if this is not a way forward, I'm happy to change the approach.

I also just noticed that the list of extensions in the template .yml does not match the actual exclude list, is that something to sync up as well?

Thanks! Yeah, it'd probably make sense to sync up the list in the .yml as well
