* chore(nodejs): Use active LTS v20 for nodejs
This updates nodejs to use the active LTS v20 from the maintenance LTS
v18. This expands compatibility with packages, adds native support for
more features, etc.
In addition, the ci-seed-chain workflow was updated to use the
.tool-version file instead of hardcoded version.
* chore(hardhat): Update hardhat for nodejs 20 support
for internal testnet deployment, record the desired deployment version
as an action variable that can be used by the checkout action instead of
using manual pull & checkout commands
* build & publish rocksdb docker images merge to master
* publish docker images on push of release version tags
NOTE: New docker image tag pattern. ALL tags now include database suffix
ex. <githash>-goleveldb, v0.25.0-alpha.1-rocksdb, master-rocksdb, etc
* update dockerfiles for better caching
* update all github action workflow versions
* improve caching of go packages
* cache docker image layers for reuse between runs
* update dockerignore to remove non-essential files
