[bug] .conanrc file is searched for wrt to the cwd instead of the recipe dir

### Environment details

* Operating System+version: Windows 11
* Compiler+version: Visual Studio 2022
* Conan version: 2.0.4
* Python version: 3.11.0

### Steps to reproduce

1. Create a project with a consumer file (e.g. conanfile.txt)
2. Create a `.conanrc` file containing an alternate conan_home
3. Navigate to an unrelated directory
4. do a `conan install` on the recipe
5. The `.conanrc` file will not be found

Looking at the source I found it starts the search from the cwd rather than the recipe directory.
