Logger disable HTML escaping

[andrewwdye]

Why are the changes needed?

When logging, html characters are escaped (JSONFormatter default). This prevents copying logged urls into the browser without modifying first.

What changes were proposed in this pull request?

This change sets logger's JSONFormatter to disable HTML escaping. While this may cause issues with HTML, this is a sane config for a logger where we don't intend to log HTML generally.

When logging with characters &, <, >

logger.Info(ctx, "foo&bar")

Before

{"json":{"src":"logger_test.go:619"},"level":"info","msg":"foo\u0026bar","ts":"2024-02-04T20:27:18-08:00"}

After

{"json":{"src":"logger_test.go:619"},"level":"info","msg":"foo&bar","ts":"2024-02-04T20:27:18-08:00"}
