[🐛 Bug]: Base64 adds new line for username and password

[bartse]

What happened?

The default max column for base64 is 76 characters. When using longer passwords in combination with a longer username I noticed this causes issues in the graphql health check.

The fix would be to add -w 0 option to base64 to override the max column. I dont think there would be any other impact of adding this option?

Below is the output of distributorProbe.sh script in debug mode

Command used to start Selenium Grid with Docker (or Kubernetes)

global:
  seleniumGrid:
    stdoutProbeLog: true
basicAuth:
  create: false
  enabled: true
  nameOverride: some-external-secret

This is an interesting case that I have yet to think about. Let me do a check and update all scripts could be impacted!

It definitely is a corner case 😬 . Thanks for checking!
