fix(plugins): update sample plugin imports to use package subpath exports

The sample plugins were importing directly from internal source paths
(`@finos/git-proxy/src/plugin.js`, `@finos/git-proxy/src/proxy/actions`)
which are not defined in the package exports map and throw
ERR_PACKAGE_PATH_NOT_EXPORTED at runtime.

Update to use the correct exported subpaths (`@finos/git-proxy/plugin`,
`@finos/git-proxy/proxy/actions`) as defined in package.json exports.

Bump package version to 0.1.2 and peer dependency to ^2.0.0-rc.6.

Depends on #1480 (fix(npm): replace .npmignore with files allowlist).
