Add CI job for Rust checks

[sam0x17]

Description : We need CI jobs implemented in the subtensor repo for auto checks for rust using cargo, specifically cargo check, cargo format, and cargo fix

AC:

• [x] CI job is implemented for all commit pushes the cargo check command
• [x] CI job is implemented for all commit pushes the cargo format command
• [x] CI job is implemented for all commit pushes the cargo fix command

right now part of #275, done but could be merged separately if needed
