[vcpkg docs] Check for documentation generation in CI (#14614) 
* [vcpkg docs] Change how documenting port functions works

Instead of using `##`, use comment blocks for documentation.

Also, add some minor docs and change RST -> MD
so we actually get docs generated.

* add CI stuff

* regenerate docs

* fix vcpkg_find_acquire_program to not use _execute_process

# vcpkg_find_fortran
Checks if a Fortran compiler can be found.
Windows(x86/x64) Only: If not it will switch/enable MinGW gfortran
and return required cmake args for building.
## Usage
```cmake
vcpkg_find_fortran(<additional_cmake_args_out>)
```

# This intentionally breaks users with a custom toolchain which do not have a Fortran compiler setup
# because they either need to use a port-overlay (for e.g. lapack), remove the toolchain for the port using fortran
# or setup fortran in their VCPKG_CHAINLOAD_TOOLCHAIN_FILE themselfs!
