Convert to ESM module

[MiSchroe]

Is your feature request related to a problem? Please describe.
More and more packages on NPM are released as ESM module, only. Older version won't be supported anymore and the risk will raise to run into secrutiy issues.

Describe the solution you'd like
A version of the adapter that is an ESM only version.
A documentation for other adapter developers that clearly marks the steps to go.

Describe alternatives you've considered
Sooner or later there will be no alternative.

Just for info:

Starting with node 22 you can simply require ESM modules:

So ESM only pacakges will not be a problem in furture, although the feature ist currently experimental. I would expect that it will be regular / stable with node 24. So it depends effort for migration.
