Add support for stable Protocol 20 release (both XDR and RPC schemas)

[Shaptic]

This prepares a stable Protocol 20 release with support for the latest XDR and RPC schemas, including:

• Renames related to the XDR: see Updating the SDKs to the stable Protocol 20 release #869 for details.
• Removing the expiration workaround as its supported in the RPC natively, now.
• Support for Node 18 and 20.
• Rename stable package under the @stellar/ organization #887

This should mirror stellar/js-soroban-client#167.

For reviewers: The best way to review this, imo, is to compare it directly to the changes that were made in soroban-client to the stable branch. Specifically, this diff covers everything needed for the latest stable version.

[sreuland]

will this pr wait on stellar-base to release first, and pin this to 10.0.0 here, or you anticipate doing another release prep pr with that bump?

[Shaptic]

I think we can merge because this won't be released, and then have a separate PR to update to the stable git ref and bump to the stable version. This will make it easier to isolate the changes that need to be reviewed! And we can use master as the gitref for E2E tests. Wdyt?

[sreuland]

yes, that works, could also git ref to the pr for e2e concerns, so whichever process is preferred, I just was curious on the pinning aspect there, thanks!

[sreuland]

lgtm, just one comment on the stellar-base ref.
