[Infra] Enable emojis in Hugo build

[vitorvasc]

• Closes Enable emojis in docs builds #7505
• Adds enableEmoji: true to the Hugo config file
• Updates the layouts/_shortcodes/alert.html shortcode to include the emojify function
  • Fixes the issue on content/en/community/end-user/_index.md, where the :female_detective: emoji is currently rendered as plain text: https://opentelemetry.io/community/end-user/#contact

hm... my understanding would be that by enableEmojify this works out of the box? So no changes to the shortcodes are required, or do I misread something in their docs:

Let me take a look once I'm done debugging the pt/pt-br i18n bundle issue.
(Btw, the alert shortcode from this repo is going away very soon since Docsy provides the one we want to use.)

I added the enableEmojify property to the config file and ran a couple tests, emojis on regular pages worked fine, but the alert shortcode was still rendering them as plain text.

Further down in the same Hugo docs page, there's a note about this:

To process an emoji shortcode from within a template, use the emojify function or pass the string through the RenderString method on a Page object

So my last test was adding the emojify function to the alerts shortcode, and that's when it started working. Ideally, it'd be great if enableEmojify handled this automatically, otherwise we might need to update all shortcodes to ensure emojis will render correctly. 🤔
