rename errors() to catchError()

[mrWh1te]

Describe the bug
The current name, while relevant, isn't very clear as to the function of the BotAction

[mrWh1te]

going forward, deprecate errors()() in next minor/patch release then delete in next major release

[mrWh1te]

unrelated, but it would be nice to add a function or something that runs and returns a value in the event an error is caught

for example, catch an error -> return an abort line signal -> restart bot with different initial pipe value

[mrWh1te]

for any devs who recognize the striking similarity between this and rxjs catchError().....

what can i say, i like the library 🤷‍♂️
