Use dtolnay/rust-toolchain@master instead of @stable

This allows passing the `toolchain` input.

+## 0.0.5 - 2023-03-19
+
+- Fix use of `dtolnay/rust-toolchain` action to allow passing a `toolchain`
+  input.
+
+## 0.0.4 - 2023-03-19
+
+- Added a new `toolchain` parameter to allow selecting a Rust toolchain other
+  than stable. This supports picking on of "stable", "beta", or "nightly".
+- Fixed binary stripping to work in more situations. Previously it depended on
+  a very specific setup plus expected to be run in the context of the matrix I
+  use for my own projects.
+- Fixed a reference to a matrix variable that should have referenced an input
+  variable.
+
+## 0.0.3 - 2023-03-17
+
+- This action now supports running the `build` and `test` commands, or both,
+  with a new input parameter, `command`. The default is `build`.
+
 ## 0.0.2 - 2023-03-05
 
 - Fixed some typos in the `README.md` documentation.
