[ruby/logger] Prefer String#[0, 1] over [0..0]

[ruby/logger] Changes to datetime formatting

2021-12-17T23:38:57+00:00

Formatting a datetime should only pertain to itself and valid datetimes do not contain a space. Should there be a desire to show show a space between the datetime and the process pid in the formatted log, this formatting logic should take place there.
Furthermore, the default datetime format is moved to a class variable to allowing this variable to be overwritten by subclasses.

Reference process PID using the Process#pid

This change will allow formatter to run from Ractors other than main.
