warning message might be better (from * 3d7e49c feat(config)!: deprecate highlight groups in config.signs)

Description

Please, don't get me wrong if this issue is not written politely enough. I am one of big fan of this project. But I am a newbie in English just like I am in vimmer.

About what

Last night, I got these warning message after updating plugins.

'signs.change.hl' is now deprecated, please define highlight 'GitSignsChange'
'signs.changedelete.hl' is now deprecated, please define highlight 'GitSignsChangedelete'
'signs.delete.hl' is now deprecated, please define highlight 'GitSignsDelete'

It breifly says I need to define some highlights. However, defining these one alone didn't resolve the warnings.

It also necessary to remove hl key from the plugin configuration:

require('gitsigns').setup({
  signs = {
    add          = { hl = 'DevIconQt', text = '+' },
    change       = { hl = 'DevIconGuix', text = '~' },

So what

I guess mentioning 'signs.change.hl' is clear enough within the context of this plugin or the vim-world. However, for someone like me, the waring could be more helpful.

I suggest adding a more detailed message or example, which would have saved me 15 minutes of confusion, and potentially help others as well.

Thank you for considering this suggestion.

Love,
