Inconsistencies in the way of mentioning /e/OS across the OS

The OS name, /e/OS, should always be written like this: /e/OS (no space in between).

So we need to have:

• /e/OS version
• /e/OS contributors
• /e/OS legal
• /e/OS supporters
• /e/OS developer options
• Enable /e/OS Telemetry
• Connect to /e/OS test channel
• Access test releases of /e/OS
• eDrive

everywhere these expressions appear in /e/OS
