Compilation error on fresh Cargo.toml that depends on near-sdk-rs 5.0.0-alpha.1

[fadeevab]

I tried to compile my project with near-sdk-rs 5.0.0-alpha.1 because of this issue #1119, however, build fails with the errors:

error: proc-macro derive panicked
 --> src/main.rs
  |
6 | #[derive(BorshSerialize, BorshDeserialize)]
  |          ^^^^^^^^^^^^^^

  = help: message: called `Result::unwrap()` on an `Err` value: Could not find `borsh` in `dependencies` or `dev-dependencies` in `/home/xxxx/yyyyy/Cargo.toml`!

Given that we re-export borsh from near-sdk, you need to hint it to borsh:

near-sdk-rs/examples/adder/src/lib.rs

Line 6 in 1343059

#[borsh(crate = "near_sdk::borsh")]
