[MashyBasker]

Description

Following the development environment creation command in CONTRIBUTING.md using micromamba gives the following error:

╭─okabe@basu ~/open-source/xeus-cpp ‹fix-build-instruction› 
╰─$ micromamba create -n xeus-cpp environment-dev.yml

    The following package could not be installed
    └─ environment-dev.yml does not exist (perhaps a typo or a missing channel).
critical libmamba Could not solve for environment specs

The command should be updated to use the -f to use the environment-dev.yml file.
