base_transactionStatus: consider removing Beta label

[Cloakie47]

The base_transactionStatus method has been labeled Beta in the docs since it was introduced in v0.3.0. Looking at the recent PR #1222 that removed the Beta label from eth_subscribe, I wanted to check whether base_transactionStatus is now stable enough to have its Beta label removed as well.

It's been available across multiple releases now and the minimum client version requirement (v0.3.0) is well behind the current stable release. If it's considered stable, happy to open a PR to remove the label.

Hi @Cloakie47, I've already opened PR #1266 that addresses this exact issue by removing the Beta label from base_transactionStatus in the FAQ table. The PR has been open since April 2nd and is ready for review. Feel free to check it out and add any feedback!
