Nested event loop error is raised in SuiAsynchClient

[CaffeineDuck]

If we initiate SuiAsynchClient before running the main event loop or in different task, it raised the nested event loop error due to asyncio.get_event_loop() and loop.run_until_complete() method being used from asyncio. The code I've mentioned is used in

class SuiAsynchClient(_ClientMixin):
    """Sui Asyncrhonous Client."""

    def __init__(self, config: SuiConfig) -> None:
        """Client initializer."""
        super().__init__(config)
        self._client = httpx.AsyncClient(http2=True)
        self._rpc_api = {}
        self._schema_dict = {}
        loop = asyncio.get_event_loop()
        loop.run_until_complete(self._build_api_descriptors())

Using the synchronous version of self_build_api_descriptors() rather than loop.run_until_complete() will fix this issue as the risk of creation of multiple loops will be gone. Also the get_event_loop() method is deprecated too.
