You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "AB-123456-CD",
  "EF-789012-GH",
  "IJ-345678-KL",
  "MN-901234-OP",
  "2023-12-15T09:45:23Z",
  "2023-01-05T14:30:15+01:00",
  "2023-06-28T22:15:40-07:00",
  "2023-11-30T08:05:30.123Z",
  "john.doe@example.com",
  "jane_smith@company.co.uk",
  "support+tickets@help.org",
  "user-name.with.dots@sub.domain.net"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
