Add opt-in semantic version equality for trailing zeros (1.0 == 1.0.0)

[Copilot]

What does this PR do?

Adds an opt-in semantic_equality parameter to enable semantic version comparison where trailing zeros are considered equivalent (e.g., "1.0" equals "1.0.0"). By default, the behavior remains unchanged for backward compatibility.

from awesomeversion import AwesomeVersion, AwesomeVersionStrategy

# Default behavior (backward compatible) - strict string comparison
AwesomeVersion("1.0") == AwesomeVersion("1.0.0")  # False

# Opt-in to semantic equality
AwesomeVersion("1.0", semantic_equality=True) == AwesomeVersion("1.0.0", semantic_equality=True)  # True

# Still False - modifiers matter even with semantic_equality
AwesomeVersion("1.0.0", semantic_equality=True) == AwesomeVersion("1.0.0-beta", semantic_equality=True)  # False

# Still False - special containers use string comparison
AwesomeVersion("beta") == AwesomeVersion("stable")  # False

# Different versions remain distinct
AwesomeVersion("1.0", semantic_equality=True) != AwesomeVersion("1.0.1", semantic_equality=True)  # True

Key Features:

• Backward compatible: Default behavior unchanged (semantic_equality=False)
• Opt-in: Set semantic_equality=True to enable trailing zeros equality
• Preserves modifiers: Versions with different modifiers remain unequal
• Special containers: Continue using string comparison

<issue_title>Versioning comparison</issue_title>
<issue_description>### The problem

A version "1.0" is not considered equivalent to "1.0.0".

@ludeeus : They are not equal so technically correct, but their meaning is the same.

Operating system

Debian

Python version

3.11

Problem-relevant code

>>> from awesomeversion import AwesomeVersion, AwesomeVersionStrategy
>>> version = AwesomeVersion("1.6.1", ensure_strategy=AwesomeVersionStrategy.PEP440)
>>> version2 = AwesomeVersion("1.6.1", ensure_strategy=AwesomeVersionStrategy.SIMPLEVER)
>>> version == version2
True

>>> version = AwesomeVersion("1.0", ensure_strategy=AwesomeVersionStrategy.SIMPLEVER)
>>> version2 = AwesomeVersion("1.0.0", ensure_strategy=AwesomeVersionStrategy.SIMPLEVER)
>>> version == version2
False
>>> version > version2
False
>>> version < version2
False

@copilot make this new logic be opt-in by setting a kwarg to true

[Copilot]

Made the semantic equality logic opt-in in commit 41c3a94. Added a semantic_equality kwarg that defaults to False for backward compatibility. Users must explicitly set semantic_equality=True to enable the trailing zeros equality behavior (e.g., AwesomeVersion("1.0", semantic_equality=True)).
