Link in README broken

Wflow version checks

• I have checked that the issue still exists on the latest versions of the docs on master here

Kind of issue

Docs are wrong

Location of the documentation

README.md

Documentation problem

Installation
For the installation enter the Pkg REPL by pressing ] from the Julia REPL, and then
pkg> add Wflow
A more detailed description, including a development install, is available here.

links to "https://deltares.github.io/Wflow.jl/dev/user_guide/install", however that page returns 404

Suggested fix for documentation

Possibly update the link to https://deltares.github.io/Wflow.jl/dev/getting_started/install.html, or point to stable instead https://deltares.github.io/Wflow.jl/stable/user_guide/install/

It is also possible to use a markdown link checker to ensure links stay alive, but they also have downsides (false positives etc.).
