📚 Description

This PR adds .jsx and .tsx to the list of extensions that are automatically resolved in the plugins directory.

Additionally, in order to avoid the meta data analysis from throwing an error (and therefore a WARN Failed to parse static properties from plugin xxxxx), I switched the esbuild transform loader from ts to tsx.

The plugin metadata test has been updated in a not-very-elegant way, but I though it was better than changing the test to .tsx "just" for 3 words.
