add support for custom emoji

resolves #2624

@derailed Hello! May you check it please?

[derailed]

@imorte Thank you for this PR!

I am not super keen on the current approach for these reasons:

1. I feel these should be part of a skin vs k9s config. As such it won't crowd up the main config and it's really a stylistic concern. Also folks could share their emojis using existing styles mechanics. So the styles could now reference a file i.e something like emojis/standard or emojis/custom-1 in their skin file and load up the respective emojiis.
2. Emojis names should be namespaced i.ie something like prompt.filter, prompt.query, status.warn, status.info
3. Not keen on defining each emoji kind as a new accessor. Better to use a generic call something like emojiFor(xxx). This allows to CRUD icons in the future with minimal effort.

What do you think?

@derailed Thanks for the response! Yes, it all sounds reasonable. I will do it this way

[derailed]

@imorte Thank you!
Also... as I just got reminded... we need to make sure that none of these are activated when noIcons flag is enabled.

@derailed done, I hope I didn't forget anything

I haven't touched this func yet

k9s/internal/render/dir.go

Line 49 in e36716a

name := "🦄 "

What do you think, is it worth spending time adding the config here now, or can we do it later?

@derailed Hi, what do you think about this PR? I can rebase and adapt it for the new version
