[MC-118258] Spelling mistakes in the 'Commandblock chain tried to execure more than x steps!' warning message

Spelling mistakes in the 'Commandblock chain tried to execure more than x steps!' warning message.

Should be:

Command block chain tried to execute more than x steps!

Set the gamerule maxCommandChainLength to 0
```
/gamerule maxCommandChainLength 0
```
Place an impulse command block with one chain command block behind it
Power the impulse command block
Look at the log

It should likely be also "Command block" (with a space)

Can confirm for MC 1.12.1.
