Adds missing config option described in
https://github.com/ipfs/kubo/issues/10803
* refactor: remove Experimental.StrategicProviding
removing experiment, replaced with Provider.Enabled
* test(cli): routing [re]provide
updated and added tests for manually triggering provide and reprovide
and making them respect global configuration flag to avoid
inconsistent behaviors
* docs: improve DelegatedRouters
* refactor: default DefaultProviderWorkerCount=16
- simplified default for both
- 16 is safer for non-accelerated DHT client
- acceletated DHT performs better without limit anyway - updated docs
