in ?scale_color_continous, add link to ?continuous_scale (#6691)

* add link to ?continuous_scale to ?scale_color_continous

Adding `continuous_scale`  to @Seealso of ?scale_color_continous allows to more easily discover potential parameters to supply in `...`  like `transform` or `limits`.

* improve see also links in docs of color scales

add scale_(color|fill)_discrete to @family color scales

remove explit @Seealso links from ?scale_(color|fill)_(continous|binned)
that are redundant due to links provided through @family

add @Seealso links for discrete_scale continous_scale and binned_scales
to scale_(fill|color)_(discrete|binned|continous) as appropiate

* add links to ?scale_(colour|fill)_(discrete|continuous|binned)

specifically, links to ?(discrete|continous|binned)_scale function in the
description of the `...` parameter

* Use `@inheritParams` for `...`
