cosmwasm latest minor versionv1.5.2

[Kynea0b]

The latest minor version of cosmwasm is used when the contract is built.

According to the rust specifications, if cargo.toml is written like this, the minor version latest will be used.

Cargo.toml

cosmwasm-schema  = "1.1.9"

Currently, v.15.* is the latest. So, this version cosmwasm-schema v1.5.2 is used.
Therefore, we need to consider and decide whether to use a fixed version of cosmwasm for the contract.
