p5-App-Sqitch: Update to 1.4.1. Changes:

- Removed the quoting of the role and warehouse identifiers that was
  added to the Snowflake engine in v1.4.0. Turns out Snowflake allows a
  warehouse to be specified in a different database, in which case dots
  are valid in the name and should not be quoted! So users must properly
  quote when necessary, but added notes to `sqitchtutorial-snowflake.pod`
  on the need to use URI escapes for special characters. Thanks to
  Patrick Sabo for the find, and to @marc-marketparts for validating
  that URI encoding works.
- Added notes on URL encoding database URLs to `sqitch-target.pod`, the
  main reference for database URLs in the Sqitch documentation.
- Fixed the output of the list of changes to be deployed or reverted to
  actually require `--verbose` twice, as described in the v1.4.0 changes,
  and not just once. Thanks to Erik Wienhold for the PR (#785)!
- Removed the duplicate change name from the output of the list of
  changes to be deployed or reverted with `-VV`. Thanks to Erik Wienhold
  for the PR (#787)!
- Fixed invalid template resolution when adding a singe change to
  multiple engines at once. Thanks to Christian Riedel for the detailed
  bug report (#795)!
- Fixed Oracle and Firebird test failures due to incorrect use of `chmod`.
  Thanks to Slaven Rezić for the report and the fix (#807)!
- Tests now require Test::Warn 0.31 or later, as newline handling issues
  cause test failures in earlier versions. Thanks to Slaven Rezić for the
  test reports and for identifying the issue.
- Updated the locale configuration to fix issues in more recent versions
  of Perl, and added tests to ensure that the sqitch CLI executes and
  properly emits localized messages (except on Windows, where the language
  codes are incompatible).
- Fixed an issue where the MySQL engine failed to recognize the MariaDB
  `mysql` client installed by Homebrew on macOS. Thanks to Carlos Ramos
  for the bug report and PR (#791)!
