refactor: Add Recognizers-Text packages to botbuilder-stdlib

[sw-joelmut]

#minor

Related PR: #4661

Description

This PR adds https://github.com/microsoft/Recognizers-Text into botbuilder-stdlib library, so it's easier to update vulnerable dependencies without introducing breaking changes.
botbuilder-stdlib is an internal library that contains helper functions which the rest of botbuilder libraries use. Therefore, we included the Recognizers-Text packages under the vendors folder, so botbuilder libraries can consume them.

Specific Changes

• Updated libraries/botbuilder-repo-utils/src/workspace.ts to search workspaces, taking into account .gitignore and the location where the command is run. Otherwise, it will cause unwanted behaviors where nested dependencies inside node_modules were considered as a workspace.
• Added all Recognizers-Text packages into the vendors folder.
  • All dependencies have been moved to botbuilder-stdlib package.json, so they are installed properly.
  • Updated all types references to match each Recognizers-Text package inside botbuilder-stdlib.

Testing

The following image shows the bot working with the new Recognizers-Text packages inside BotBuilder.
