[Bug] crypto/defi/sratio: Remove scientific notation in Chart title

[montezdesousa]

Description

Tries to solve #1937 by just removing sratio command from the crypto/defi choices and help. Scientific notation was triggered by unreasonable Luna staking ratio coming from Terra FCD. Didn't remove call_sratio or any other related functions, since source data might be fixed in the future. Please let me know if I should remove this as well as any other related code.
