[Bug]: Devbox is inconsistent about adding `plugin_version` into devbox.lock

[mdwn]

Current Behavior (bug) When adding certain dependencies to the devbox.lock file, devbox is inconsistent about adding the plugin_version field depending on the current state of both the .devbox directory and the devbox.lock file.

To see this behavior, try the following from a devbox enabled project with both the .devbox directory and the devbox.lock file present:

Description	Command	Result
Remove both devbox.lock and .devbox	rm -rf devbox.lock .devbox && devbox install	No plugin line.
Leave .devbox directory intact	rm devbox.lock && devbox install	No plugin line.
Leave devbox.lock intact	rm -rf .devbox && devbox install	Plugin line appears.

Expected Behavior (fix) The plugin_version line should be consistently applied regardless of the current state of the .devbox directory and the devbox.lock file.

Did this get fixed? It is causing issues with the way github actions caching works as it uses the lock file in the cache hash
