fix: documentation sample code did not compile

[pconstantinou]

The README.md file provides sample code that does not compile because the import declaration (github.com/twilio/twilio-go) ends with the repository nametwilio-go but the code uses the package name twilio. @see https://go.dev/ref/spec#Import_declarations

Top address this, I have updated the example code to the alias the package name to "twilio".

The sample documentation here: https://www.twilio.com/docs/libraries/go has the sample problems.

Hi @pconstantinou , the sample code should compile as the package name for the functions is twilio. Could you provide more details, code samples, and links for what you're trying to accomplish?

Sorry, my environment was screwed up. When fixed, the aliasing was not needed.
