Error Prone 2.26.0

Warning: This release contains a bug, please use 2.26.1 or newer instead.

Changes:

• The 'annotations' artifact now includes a module-info.java for Java Platform Module System support, thanks to @sgammon in #4311.
• Disabled checks passed to -XepPatchChecks are now ignored, instead of causing a crash. Thanks to @oxkitsune in #4028.

New checks:

• SystemConsoleNull: Null-checking System.console() is not a reliable way to detect if the console is connected to a terminal.
• EnumOrdinal: Discourage uses of Enum.ordinal()

Closed issues: #2649, #3908, #4028, #4311, #4314
