Issue #3314451 by jonathan1055: Eslint coding standards faults - add .prettier config files

# These files fail eslint standards. In due course they will be fixed and then

# removed from this ignore file.

# See https://www.drupal.org/project/scheduler/issues/3314451

drupalci.yml

js/scheduler_default_time.js

js/scheduler_default_time_8x.js

js/scheduler_vertical_tabs.js

 No newline at end of file

// This file does not strictly need to exist in contrib, because core's eslint

// config will be inherited from further up in the directory hierarchy. However,

// eslint does not have a 'sniff all files' parameter, but having this file (and

// making a temporary change to it) will cause all files to be checked.

// See https://www.drupal.org/project/scheduler/issues/3314451
