Update major version of https-proxy-agent

[tkandr]

Unfortunately, https-proxy-agent@2 depends on node-agent-base@4, which changes the functionality of core https.request and drops support of https.request(url[, options][, callback]) signature. Because of this, some other modules, which are using https.request(url[, options][, callback]) are not working correctly (In my case, It's got).

This issue is impacting the usage of webdriverIO v6 with Browserstack tunnel.
The session request are sent by got library using a proxy over https. The service hostname get changed from hub-cloud.browserstack.com to 127.0.0.1 due to node-agent-base@4 override.
Forcing the npm package resolution to "https-proxy-agent": "^5.0.0" fix the issue.
Could you please upgrade your project to use a safe version of https-proxy-agent?
