Use p-defer-es5 instead

[compulim]

Fixes #3977.

Changelog Entry

Fixed

• Fixes #3977. Fix bundle not work in Internet Explorer 11 due to p-defer, by @compulim, in PR #3978

Description

When working on #3974, we imported p-defer instead of p-defer-es5. Since our build pipeline is configured not to transpile anything from node_modules/*, thus, we are putting non-ES5 code in webchat-es5.js.

Design

Import from p-defer-es5 instead. In other part of our code, we also import p-defer-es5 instead. It is a package that transpile p-defer on npm install-time.

Specific Changes

• Update packages/bundle/src/speech/CustomAudioInputStream.ts to use p-defer-es5 instead

• I have added tests and executed them locally (Will test it in release testing)
• I have updated CHANGELOG.md
• I have updated documentation
