Fix plugin import from plugin registry

[royalnine]

Describe the bug

Importing plugins from the plugin registry doesn't work on develop. Due to the fact that the plugin names changed from @elizaos/plugin-<> to @elizaos-plugins/plugin-<>

To Reproduce

1. npx elizaos plugins add @elizaos-plugins/plugin-compass
2. pnpm run build
3. add @elizaos-plugins/plugin-compass to character file
4. [Optional], make this print the error stack:

elizaLogger.error(
                        `Failed to import plugin: ${plugin}`,
                        importError.stack || importError
                    );

Expected behavior

Plugin import should work on the new plugins from the plugin registry
