Update twilio dependency in serverless-runtime-types

[Humberd]

Currently serverless-runtime-types project uses a twilio dependency version 3.

serverless-toolkit/packages/serverless-runtime-types/package.json

Line 33 in fd6235a

"twilio": "^3.60.0"

However, the newest one is version 4.
If you install both newest versions in your project then you will get conflicts:

Type 'import("D:\\Repositories\\flexfunctions\\node_modules\\@twilio-labs\\serverless-runtime-types\\node_modules\\twilio\\lib\\rest\\api\\v2010\\account\\incomingPhoneNumber").IncomingPhoneNumberInstance' 
is not assignable to type 'import("D:\\Repositories\\flexfunctions\\node_modules\\twilio\\lib\\rest\\api\\v2010\\account\\incomingPhoneNumber").IncomingPhoneNumberInstance

Thank you so much for opening your first issue in this project! We'll try to get back to it as quickly as possible. While you are waiting...here's a random picture of a corgi (powered by dog.ceo)

Maintainers, please update the typings or provide some kind of warning about this issue.

Maybe add twilio: 3.60.0 as a peer dependency so we can at least know that it is the required version and not 4.x
