Completion script gives me a syntactic error

When using _source_ command for adding **dotnet-suggest-shim** to bash, I get the following error:

`$: source .bashrc
bash: /home/Weinman/.dotnet-suggest-shim.bash: línea 1: error sintáctico cerca del elemento inesperado `$'\r''
'ash: /home/Weinman/.dotnet-suggest-shim.bash: línea 1: `_dotnet_bash_complete() `

This happens after having followed the instructions [here](https://github.com/dotnet/command-line-api/blob/main/docs/dotnet-suggest.md)
