[release] Bumped to release 10.0.0

[Aryamanz29]

Bumps the SDK from 9.11.0 → 10.0.0 (major — a breaking behavior change in AtlanTag).

Updates pyatlan/version.txt and prepends the HISTORY.md release notes.

Included since 9.11.0

New features

• client.requests + client.inbox (feat: client.requests + client.inbox — approve/reject both request systems programmatically (BLDX-1611) #1003, BLDX-1611): manage both of Atlan's approval systems — the classic Requests module and the governance-workflow Inbox (first SDK to support the latter). Sync + async parity.
• CsaUberAssetExportBasic (feat: v3 app builder for Asset Export (Basic) + migration pointers on all legacy packages (AICHAT-1588) #1004, AICHAT-1588): v3 app builder for Asset Export (Basic) on native-app tenants, plus deprecation pointers on every legacy model.packages class that has a typed v3 builder.

Breaking changes

• AtlanTag propagation defaults now reach the wire (fix: AtlanTag propagation defaults now reach the wire (BLDX-1589) — breaking behavior change #1001, BLDX-1589): a bare AtlanTag(type_name=t) now serializes its documented propagation defaults (propagate=false, …) instead of letting the server apply propagate=true. Tags built without explicit propagation settings will no longer propagate by default.
