Replace deprecated catch operator with try...catch

[bjosv]

The catch operator is deprecated and OTP 29 will emit compiler warnings for its use.
Replaced catch with try...catch and start building with OTP 29.0-rc2 in CI.

Good catch(!) but we will probably delete ered_connection. It's deleted in the feature branch single-process-client. If we merge this PR now, it will give us conflicts.

Do you want to open this PR against the feature branch instead? Otherwise wait until it's merged.

I can wait until the feature branch is merged, then I can replace 29.0-rc2 with 29.0.1 depending on the timeframe.
