bug: checkhealth warns when plugin configuration uses key 'submodules'

[gongfarmer]

Did you check docs and existing issues?

• I have read all the lazy.nvim docs
• I have searched the existing issues of lazy.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

v0.10.0-dev-43b0e27

Operating system/version

linux, debian 11

Describe the bug

The lazy.nvim configuration docs include the key 'submodules', but the health check flags this key as invalid and warns about its usage.

Also, I diffed the list of configuration keys in the docs against the valid keys list in lua/lazy/health.lua and found 2 keys that are allowed by health check but undocumented;
These are: deactivate, import. I don't know if this is considered a bug, just FYI.

Steps To Reproduce

1. Configure a plugin with the submodule key:

  {
    'stevearc/aerial.nvim',
    submodules = false, -- can't reach github urls behind corporate firewall
    config = true
  },

2. Run nvim, and :checkhealth lazy

Expected Behavior

Expected: no errors from :checkhealth lazy

Actual:

lazy: require("lazy.health").check()
lazy.nvim
- OK Git installed
- OK no existing packages found by other package managers
- OK packer_compiled.lua not found
- WARNING {aerial.nvim}: unknown key <submodules>

Repro

local lazypath = vim.fn.stdpath 'data' .. '/lazy/lazy.nvim'
vim.opt.rtp:prepend(lazypath)
require('lazy').setup {
  {
    'stevearc/aerial.nvim',
    submodules = false, -- can't reach github urls behind corporate firewall
  },
}
