feat: add startup telemetry status logs

[abhijnyan-codes]

Closes #9299

Added log messages to runTelemetry() to inform users of telemetry status at startup:

• Keystone Telemetry is disabled (running in CI)
• Keystone Telemetry is disabled (NODE_ENV is production)
• Keystone Telemetry is disabled (via KEYSTONE_TELEMETRY_DISABLED env)
• Keystone Telemetry is disabled (via opt-out)
• Keystone Telemetry is enabled

please use the log function used by the rest of file, not console.log

please change the prefix, s/Keystone Telemetry is/telemetry is

Thanks for the feedback! I noticed the existing log() function only outputs when KEYSTONE_TELEMETRY_DEBUG=1, which would hide these status messages from regular users. Should I use log() anyway, or is there another logging utility I should use instead?

[dcousens]

ah, true, sorry, I think we want the logging approach used by the rest of the codebase for this - not the log from this file

@abhijnyan-codes at the same time as this, did you want to add support to opt-out if the user has DO_NOT_TRACK=1 in the environment too?

[abhijnyan-codes]

Added DO_NOT_TRACK=1 support as well.

Thanks @abhijnyan-codes, if you can add a changeset, I will resolve the last remaining tidbits
