Speed up async_render_with_possible_json_value

[bdraco]

Proposed change

While contextlib.suppress is a bit more compact, it is much slower than try/except since python3.11+ has near zero cost try which is much cheaper than creating a context manager, entering, and exiting it. In this case we will almost never raise an exception here and this function is called 1000s (10000+ on larger mqtt setups) of times at startup.

In this case it was nearly 1/3+ of the run time of this function.
