fix: [#4520] Upgrade restify to fix error on Node version 18+

[ceciliaavila]

Fixes #4520

Description

This PR upgrades the restify dependency to version 11.1.0 to avoid the error on Node 18+.
It also updates the target in TS bots, as the new version of restify introduced a breaking change.
Additionally, it upgrades botbuilder packages to version 4.20.0 and fixes an eslint issue in the core bot's index.ts.

Specific Changes

• Updated remaining TS and JS bots to use restify version 11.1.0.
• Upgraded botbuilder packages to version 4.20.0.
• Updated the tsconfig.json's target property to es2017.
• Fixed a lint issue in templates/core/index.ts.

Testing

These images show the generated bots working and the tests in core-with-tests passing.
