feat(nvm)!: make `lazy` and `autoload` options compatible

BREAKING CHANGE: Prior to this commit, if `lazy` and `autoload` options
were enabled at the same time, `lazy` was getting overriden and only
`autoload` was taken into account.
Now they work together and `autoload` will be enabled after `nvm` has
been lazy-loaded.

Closes #11690

 #### `.nvmrc` autoload
 
-Note: _this option cannot be used at the same time as `lazy`. `autoload` will override it and load `nvm` at
-startup._
+Note: _if used at the same time as `lazy`, `autoload` will start working only after nvm has been lazy-loaded_
 
 If set, the plugin will automatically load a node version when if finds a
 [`.nvmrc` file](https://github.com/nvm-sh/nvm#nvmrc) in the current working directory indicating which node
