Update wgAutoCreateTempUser config defaults

Why:
* The default value of wgAutoCreateTempUser has not changed since
  the decision to use a different prefix for temporary accounts
  (T332805).
* The default needs to be updated to reduce the number of overrides
  in operations/mediawiki-config and also to make the development
  experience more consistent with what is happening on WMF
  production.

What:
* Update the wgAutoCreateTempUser default in the following ways:
** Set expireAfterDays as 365
** Set notifyBeforeExpirationDays as 10
** Set genPattern and reservedPattern to '~$1'
** Set matchPattern to null, which will mean that the genPattern
   is used as the value.
* Update RealTempUserConfig::getPlaceholderName to add the year to
  the placeholder name so that if the match pattern includes the
  first digit of the year, then the placeholder name still is
  considered a valid temporary account username.
* Replace modifications of the wgAutoCreateTempUser config in
  integration tests with a use of the TempUserTestTrait to make
  the code cleaner and make it easier to find tests that relies on
  the values in wgAutoCreateTempUser.
* Update multiple tests to handle the new defaults for the config.
