Update iniconfig to 2.3.1

[pyup-bot]

This PR updates iniconfig from 2.0.0 to 2.3.1.

Changelog

2.3.1

=====

* fix quadratic parse time for values with many continuation lines (78, regarding 77)
* strip a leading UTF-8 BOM when reading INI files, which previously raised ``ParseError`` (76)
* internal: ``iniconfig._parse.ParsedLine.value`` is now a list of lines

2.3.0

=====

* add IniConfig.parse() classmethod with strip_inline_comments parameter (fixes 55)
- by default (strip_inline_comments=True), inline comments are properly stripped from values
- set strip_inline_comments=False to preserve old behavior if needed
* IniConfig() constructor maintains backward compatibility (does not strip inline comments)
* users should migrate to IniConfig.parse() for correct comment handling
* add strip_section_whitespace parameter to IniConfig.parse() (regarding 4)
- opt-in parameter to strip Unicode whitespace from section names
- when True, strips Unicode whitespace (U+00A0, U+2000, U+3000, etc.) from section names
- when False (default), preserves existing behavior for backward compatibility
* clarify Unicode whitespace handling (regarding 4)
- since iniconfig 2.0.0 (Python 3 only), all strings are Unicode by default
- Python 3's str.strip() has handled Unicode whitespace since Python 3.0 (2008)
- iniconfig automatically benefits from this in all supported versions (Python >= 3.10)
- key names and values have Unicode whitespace properly stripped using Python's built-in methods

2.2.0

=====

* drop Python 3.8 and 3.9 support (now requires Python >= 3.10)
* add Python 3.14 classifier
* migrate from hatchling to setuptools 77 with setuptools_scm
* adopt PEP 639 license specifiers and PEP 740 build attestations
* migrate from black + pyupgrade to ruff
* migrate CI to uv and unified test workflow
* automate GitHub releases and PyPI publishing via Trusted Publishing
* include tests in sdist
* modernize code for Python 3.10+ (remove __future__ annotations, TYPE_CHECKING guards)
* rename _ParsedLine to ParsedLine

2.1.0

=====

* fix artifact building - pin minimal version of hatch
* drop eol python 3.8
* add python 3.12 and 3.13
