Simplify pyparsing dependency by requiring version >2.0.0

[Copilot]

Reduces external dependencies from 8 to 7 and simplifies pyparsing version handling by requiring pyparsing >2.0.0.

Changes

• Remove packaging: Eliminated the need for the packaging dependency by requiring pyparsing >2.0.0 directly
• Update pyparsing requirement: Changed from pyparsing>=1.5.7 to pyparsing>2.0.0 in pyproject.toml
• Remove version check: Removed version comparison logic and conditional syntax, now uses pyparsing 2.0+ syntax directly
• Keep tzlocal: Maintains the existing tzlocal dependency for timezone detection

Implementation

Simplified grammar initialization (graphite_render/render/grammar.py):

# Direct use of pyparsing 2.0+ syntax - no version check needed
expression <<= Group(template | call | pathExpression)('expression')
grammar <<= expression

The version check and _compare_version() function have been completely removed since all installations are now guaranteed to have pyparsing >2.0.0.

Benefits

• One fewer external dependency (packaging removed)
• Cleaner, simpler code without version compatibility checks
• Guaranteed consistent behavior across all installations
• Reduced maintenance burden

All 486 tests pass. No security alerts.

@copilot Keep tzlocal and revert back the changes associated

Reverted tzlocal changes in commit ca6215f. The tzlocal dependency is now kept and used for timezone detection as before. The packaging dependency removal is maintained.

@copilot Update pyparsing to >2.0.0 and remove the version check in the code

Updated pyparsing requirement to >2.0.0 and removed the version check in commit e4a2490. The _compare_version() function has been removed, and the grammar now uses the pyparsing 2.0+ syntax directly.
