Update ruby-head WASI gem lockfile

[ledsun]

Summary

• update the ruby_wasm lockfile entry from 2.8.1.dev to 2.10.1
• update the js lockfile entry and dependency constraint to 2.10.1
• prevent bundle install during ruby-head-wasm-wasi builds from rewriting Gemfile.lock

Background

The last commit that updated packages/npm-packages/ruby-head-wasm-wasi/Gemfile.lock was cc57b30 (rake bump_dev_version), which changed its ruby_wasm and js entries from 2.8.0 to 2.8.1.dev.

This appears to be a repeated release-version update omission rather than a one-time mismatch. The bump_version task runs bundle install for every entry in NPM_PACKAGES that has a Gemfile, and ruby-head-wasm-wasi is explicitly one of those entries. However, each of the following release commits updated the project versions and the equivalent ruby-head-wasm-wasip2 lockfile while leaving ruby-head-wasm-wasi/Gemfile.lock unchanged:

• ae47c49: Release 2.9.0
• 246106d: Release 2.9.3
• d3089aa: Release 2.9.4
• f1c909b: Release 2.10.0
• cbb1e84: Release 2.10.1

As a result, the head WASI lockfile remained at 2.8.1.dev across all five releases. This PR aligns it directly with the current 2.10.1 versions.
