[BruceHaley]

Fixes #minor

Description

Fixes the high severity follow-redirects vulnerability listed in these 2 CG alerts:
https://fuselabs.visualstudio.com/SDK_v4/_componentGovernance/112352/alert/6373557?typeId=10422422
https://fuselabs.visualstudio.com/SDK_v4/_componentGovernance/112352/alert/6373574?typeId=10422422

Vulnerability: follow-redirects 1.5.10
-- Recommendation: Upgrade follow-redirects from 1.5.10 to 1.14.7
Vulnerability: follow-redirects 1.14.4
-- Recommendation: Upgrade follow-redirects from 1.14.4 to 1.14.7

The initial follow-redirects dependency tree looked like this:

C:\src\botbuilder-js>npm ls follow-redirects
[email protected] C:\src\botbuilder-js
`-- @azure/[email protected]
  `-- [email protected]
    `-- [email protected]

I fixed it with the command:
yarn upgrade @azure/[email protected]
...resulting in the dependency being eliminated:

C:\src\botbuilder-js>npm ls follow-redirects
[email protected] C:\src\botbuilder-js
`-- (empty)

Testing

I tested the fix in these 4 Sample-Js E2E test runs:
Sample-Js-CoreBot-Linux-Test-yaml
Sample-Js-CoreBot-Win-Test-yaml
Sample-Js-EchoBot-Linux-Test-yaml
Sample-Js-EchoBot-Win-Test-yaml
