WIP: chore: Release version 0.12.4

_PROST!_ is a [Protocol Buffers](https://developers.google.com/protocol-buffers/) implementation for the [Rust Language](https://www.rust-lang.org/). `prost` generates simple, idiomatic Rust code from `proto2` and `proto3` files.

This patch updates brings a few new features and fixes:

- Bump MSRV to 1.70 (minimum supported Rust version)
- Rename cargo feature `prost-derive` to `derive` (tokio-rs#992)
- Add @generated comment on top of generated files (tokio-rs#935)
- Optimize implementation of prost::Name when generated by prost-build (tokio-rs#956)

## Dependencies
- build(deps): Allow itertools 0.12 (tokio-rs#948)
- build(deps): Allow heck 0.5 (tokio-rs#1012)
- build(deps): Allow multimap 0.10 (tokio-rs#1013)

## Documentation
- Improve protoc not found error message (tokio-rs#937)
- build: Add development container config (tokio-rs#949)
- docs: Fixed README typos (tokio-rs#952 / tokio-rs#967 / tokio-rs#970)

## Internal
- chore: Fix minimal versions (tokio-rs#920)
- fix: fq_message_name should begin with one dot (tokio-rs#981)
- improve encode_varint performance by bounding its loop (tokio-rs#940)
- style: Remove duplicate function call (tokio-rs#989)
- test: Improve test decode_varint_slow (tokio-rs#977)
- chore: Add dep: prefix to feature dependencies (tokio-rs#919)
- Minor clippy lint fixes. (tokio-rs#1006)
- chore: Use taiki-e/install-action to setup cargo-machete (tokio-rs#909)
- chore: Remove which dependency. (tokio-rs#962)
- chore: Update to actions/checkout@v4 (tokio-rs#910)
