fix: remove index on application create call in beta composer

[uhudo]

Proposed Changes

• There is an error when using creating an application with beta/composer.py because the parameter index is passed to ApplicationCreateTxn.
• Remove passing index in beta/composer.py when creating an application.

Hello @uhudo thank you for submitting the PR, the beta namespace is not the final implementation accommodating full feature parity with algokit-utils-ts. There is a significant rework going on to get algokit-utils-py up to speed with all latest algokit-utils-ts public interfaces and abstractions. To track progress refer here https://github.com/algorandfoundation/algokit-internal/issues/42. I will merge your PR but be aware that from v3 of py sdk there may be further breaking changes in beta namespace, as for all of the existing stateless functions in v2 -> similar to utils-ts they will be supplemented with detailed deprecation guides

Hey @aorumbayev, thanks for the info. I wasn't aware of the ongoing changes. The link you put to track the progress is to an algokit-internal repo, which is giving me 404 error.

I see, that issue was aggregating a set of public issues already defined on this repo, here is the full breakdown

Work represented in items below:

• Documentation and type hinting validation for utils-ts compliant utils-py functionality #117
• Implement AppClient interface and related abstractions #116
• Implement TransactionComposer interface and related abstractions #115
• Implement AppManager interface #114
• Implement AppDeployer & AppFactory interfaces #113
• Implement AssetManager interface #112
• Implement AccountManager interface #111
• Implement AlgorandClient interface #110

@uhudo you should be able to access those to track progress 👍
