npm package version needs to be updated

[ahonn]

I noticed that the package version available at https://www.npmjs.com/package/@mempool/mempool.js is still at v2.3.0 which was released two years ago. Although the main branch has been updated, there has been no new npm version released. Due to this, certain interface parameters such as after_txid are not yet supported in v2.3.0.

Can you update the npm package version based on the changes made in the main branch?
