Failed to build Move modules: Compilation error.

The [pachage] in Move.toml is:

[package]
name = "my_first_package"
edition = "2024.beta" # edition = "legacy" to use legacy (pre-2024) Move
# license = ""           # e.g., "MIT", "GPL", "Apache 2.0"
# authors = ["..."]      # e.g., ["Joe Smith (joesmith@noemail.com)", "John Snow (johnsnow@noemail.com)"]

The edition should be annotated!!!
