"the" plugin uses incorrect regex

[gschmidl]

Problem

Running this command:

~ ❯ beet move artist:trance -p
Moving 40 items.
M:\TET - Travailleur En Trance\[2008] Cobra Coded Escalation\01-01 - Cobra Reporting In.mp3
  -> M:\‒ Travailleur En Trance, TET\[2008] Cobra Coded Escalation\01-01 - Cobra Reporting In.mp3

Led to this problem:

"TET" is recognized by the "the" plugin as something it should move. This is because the regex used in the.py, line 26, is

PATTERN_THE = u'^[the]{3}\\s'

which matches "TET". It should probably be:

PATTERN_THE = u'^the\\s'

Setup

• OS: Windows 10 2004
• Python version: 3.8
• beets version: latest trunk
• Turning off plugins made problem go away (yes/no): obviously, if I disable 'the' it no longer does this
