Remove v30 SDK type names migration entry

[leighmcculloch]

What

Remove the v30 migration guide entry about naming types, events, and errors with soroban-sdk type names.

Why

The migration guide is for meaningful breaking changes, and this isn't one: contracttype already rejected these names and it was just the way that the rejection happened that changed.

Known limitations

N/A

SemVer Change

🟢 Approval recommended

Classification: patch. The PR only removes a documentation page from the _migrating docs module.

• soroban-sdk/src/_migrating.rs and the deleted _migrating/v30_sdk_type_names.rs contain only doc comments and the pub mod declaration for them. No code, macro output, manifests or features changed. Rule: documentation changes are patch.
• The removed pub mod v30_sdk_type_names was added during the unreleased v30 cycle. There is no v30* tag, only v29.0.1, so no published release exposed it.
• .semver/cargo-semver-checks.txt failed with unsupported rustdoc format v61 (supported: v55–v57). The classification is from the diff alone.

To check: if v30_sdk_type_names shipped in a pre-release, deleting a public module would count as major under "removing public items".

This classification is advisory. The author and reviewer decide the release type.
