Inconsistent naming of presets, specifically the helpers: config preset

[HonkingGoose]

What would you like Renovate to be able to do?

The sidebar of our docs page uses the singular form for the preset name: Included presets -> Helper Presets.
But the Helper Presets themselves use the plural form, for example: helpers:disableTypesNodeMajor.

All other presets use the singular form, like group:, monorepo: etc.

I don't know why we use the plural form for for the helpers: preset? Maybe there's a good reason that I'm missing.

Did you already have any implementation ideas?

Option 1: Rename side bar item from Helper Presets -> Helpers Presets, this way sidebar heading and preset prefix match again.

Option 2: rename Helper Presets from plural to singular form. So from helpers: to helper:. Keep sidebar as-is.

We can rename from helpers: to helper: and retain a permanent redirect
