try to better highlight donations and sponsorships options ...

... and to better explain why they are required.

Please don't say "someone else will help the project, I'll just use it"

+## Sponsors

+If you find SFTPGo useful please consider supporting this Open Source project.
+Maintaing and evolving SFTPGo is a lot of work - easily the equivalent of a full time job - for me.
+I'd like to make SFTPGo into a sustainable long term project and would not like to introduce a dual licensing option and limit some features to the proprietary version only.
+If you use SFTPGo, it is in your best interest to ensure that the project you rely on stays healthy and well maintained.
+This can only happen with your donations and [sponsorships](https://github.com/sponsors/drakkan) :heart:
+
+If you just take and don't return anything back, the project will die in the long run and you will be forced to pay for a similar proprietary solution.
+
+More [info](https://github.com/drakkan/sftpgo/issues/452).
+
+Thank you to our sponsors!

Please note that even if set using an environment variable this field is read at SFTPGo startup and not at runtime. This is not a license key or similar, the purpose here is to prevent anyone who can access to the initial setup screen from creating an admin user. Default: blank.

 - **"telemetry"**, the configuration for the telemetry server, more details [below](#telemetry-server)
   - `bind_port`, integer. The port used for serving HTTP requests. Set to 0 to disable HTTP server. Default: 0
