Describe the bug

For some REST API endpoints we use Google Cloud API Custom Methods URL design like /api/resource:customVerb.

These worked with axios prior to 0.27.1 but now they result in an error like:

AxiosError { message: "Unsupported protocol /api/resource:', code: "ERR_BAD_REQUEST", ... }

To Reproduce

Try to have axios get a relative URL with a colon in it, e.g.

axios.get("/api/resource:customVerb");

Expected behavior

Should continue working as it did before version 0.27.1.

Environment

• Axios Version: 0.27.1
• Browser: Microsoft Edge 100.0.1185.50
• Node.js Version: 16.14.2
• OS: Windows 10 Pro
