Upgrade to Apache HttpClient 5.4

This commit also updates the external Javadoc link to avoid the following
warning in the build.

URL https://hc.apache.org/httpcomponents-client-5.2.x/current/httpclient5/apidocs/package-list was redirected to https://hc.apache.org/httpcomponents-client-5.4.x/current/httpclient5/apidocs/package-list

Closes gh-33587
