Fix typo in the command example in the comments Update main.rs

[famouswizard]

I noticed a typo in the comment section of the code. Specifically, in the command example:

//! cargo run -p beacon-api-beacon-sidecar-fetcher --node -- full

There is an extra space between --node and full, which could cause confusion or errors when running the command. The correct version should be:

//! cargo run -p beacon-api-beacon-sidecar-fetcher --node --full

I’ve fixed this typo to ensure the command is properly formatted and avoids any potential issues when users follow the example.
