Fail to verify basic flipper contract

[deuszx]

I've done the following:

1. Build the ink-verifier-image locally from main branch.
2. Create a basic flipper contract cargo contract new flipper
3. cd flipper and run build-verifiable-ink -t develop .

The result is that it fails to build the package:

  flipper build-verifiable-ink -t develop .

error: failed to compile `cargo-contract v2.0.2`, intermediate artifacts can be found at `/tmp/cargo-installbjuGr0`

Caused by:
  package `ink_env v4.2.0` cannot be built because it requires rustc 1.68 or newer, while the currently active rustc version is 1.66.1
  Try re-running cargo install with `--locked`

Notice the errors at the beginning.

Realted #6

[deuszx]

Most probably, adding --locked to cargo install ... cargo-contract will solve the issue.

hello @deuszx ! both the problems (#6 and the --locked flag) have been resolved in the latest release, particularly, in this commit: a397b0d
