Cannot install go package due to capitalization in mod.go

Hi! I'd like to try your application but could not installed it locally on Fedora 38:

$ go install github.com/rh12503/triangula-cli/triangula@latest
go: github.com/rh12503/triangula-cli/triangula@latest: github.com/rh12503/triangula-cli@v0.0.0-20210520132201-603b709907d8: parsing go.mod:
	module declares its path as: github.com/RH12503/Triangula-CLI
	        but was required as: github.com/rh12503/triangula-cli

I hope fixing the capitalization fixes this issue. Also, if it works, it'd be nice to adjust the README.md to use "install" instead of "get".

Cheers,
Maximilian.
