feat: SDK update for version 29.1.0

[ChiragAgg5k]

This PR contains updates to the SDK for version 29.1.0.

What's Changed

• Added: optional state parameter on createOAuth2Token, returned unchanged on the success and failure URLs

This is a patch on top of 29.0.0: it adds only the state parameter from appwrite/appwrite#14157, plus the version bump and changelog. main is already at 30.0.0-rc.2, so this targets a 29.x branch cut from tag 29.0.0; 29.1.0 is released from 29.x.

The new state forwarding behavior needs regression coverage in the existing account tests.

Adds an optional OAuth2 state parameter to both object-style and positional createOAuth2Token calls and forwards it in the request query. Updates the example, changelog, package metadata, and client version identifiers for 29.1.0.

### Issue 1
src/services/account.ts:3013-3015
**Add regression coverage for OAuth2 state forwarding**

The existing `createOAuth2Token` test in `test/services/account.test.js:1130` calls only the provider argument and returns a fixed redirect, so it would still pass if state were dropped. Please cover both calling styles, verifying the outgoing URL's decoded state (including query-special characters) and omission when state is undefined.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.
