Apache Iceberg Rust version

Describe the bug

Currently in ci's msrv check, we have a step to generate lock file, which cause inconsistency between ci and local env.

To Reproduce

See

iceberg-rust/.github/workflows/ci.yml

Line 142 in 4531203

- name: Generate minimal versions lockfile

Expected behavior

We already checked in Cargo.lock, this is unncessary.

Willingness to contribute

I can contribute a fix for this bug independently

Hi, our Cargo.lock file is already kept up to date, ensuring that we don’t break when using the latest versions of our dependencies. However, this test is designed to generate lock files using the minimal versions specified in Cargo.toml. This helps verify that the versions listed in Cargo.toml are correct and function as expected. It’s expected that this test does not use our existing lock files.

If this test fails, it indicates that the versions specified in Cargo.toml are incorrect. For example, specifying uuid = "1.1" is incorrect if users cannot build iceberg-rust with uuid = "=1.1.0" and instead require a higher version.

Yes, this is intentional, a.k.a. minimum-(dependency)-version-testing

Thanks @Xuanwo @xxchan 's discussion, it's reasonable to me.
