fix: pin Motoko recipe to immutable commit SHA

Both Motoko examples now point to the specific commit of the fix branch
rather than the branch name, which is mutable. Swap to a stable
@dfinity/motoko release tag once dfinity/icp-cli-recipes#26 ships.

 ### Motoko recipe version
-`motoko/who_am_i/icp.yaml` pins a raw GitHub URL to pick up `[moc] args` support before it ships in a stable release. Once https://github.com/dfinity/icp-cli-recipes/pull/26 merges and a new `@dfinity/motoko` version is released, update:
-- `motoko/who_am_i/icp.yaml`
-- `motoko/hello_world/icp.yaml`
+Both `motoko/who_am_i/icp.yaml` and `motoko/hello_world/icp.yaml` pin a specific commit SHA of the Motoko recipe to pick up `[moc] args` support from `mops.toml` before it ships in a stable release:

+Tracked in: https://github.com/dfinity/icp-cli-recipes/pull/26

+Once that PR merges and a new `@dfinity/motoko` version is released, replace the raw URL in both files with the versioned tag (e.g. `@dfinity/motoko@vX.Y.Z`).
