Update e2b_charts dependencies for numpy 2 support

[mishushakov]

Summary

• Relaxes numpy constraint from ^1.26.4 to >=1.26.4 to allow numpy 2.x compatibility
• Bumps matplotlib, pydantic, pytest, and python-dotenv to latest versions
• Regenerates poetry.lock

Test plan

• Run poetry install in chart_data_extractor/ and verify resolution
• Run poetry run pytest to ensure tests pass

Note

Medium Risk
Upgrades core numeric/plotting dependencies (notably numpy 2.x and matplotlib 3.10), which can introduce subtle runtime/ABI and rendering behavior changes. Lockfile regeneration and updated Python/version markers may affect dependency resolution across environments.

Overview
Updates e2b-charts to newer dependency versions, including moving to numpy 2.x, bumping matplotlib, pydantic, pytest, and python-dotenv, and regenerating poetry.lock accordingly.

Adjusts pie chart angle extraction in charts/pie.py to coerce wedge.theta1/theta2 to float before Decimal arithmetic, improving compatibility with updated Matplotlib/NumPy numeric types.

Adds a Changeset marking @e2b/data-extractor for a major release due to the dependency updates.

Test run, but I think I will explicitly update it to numpy v2 to see if it's not breaking the chart extraction (since our other PR requires numpy 2)

Updated PR description:

## Summary
- Upgrades numpy from `^1.26.4` to `^2.2.6` (breaking change - requires numpy 2.x)
- Bumps matplotlib to `^3.10.3`, pydantic to `^2.9.1`, pytest to `^8.3.5`, and python-dotenv to `^1.2.1`
- Fixes pie chart angle extraction in `charts/pie.py` to handle numpy 2.x's removal of implicit conversion from numpy.float32 to Decimal by wrapping `wedge.theta1` and `wedge.theta2` with `float()` before `Decimal()` conversion
- Regenerates poetry.lock with numpy 2.x dependencies
- Changeset marked as **major** release due to breaking numpy version requirement change

## Test plan
- [x] Run `poetry install` in `chart_data_extractor/` and verify resolution
- [x] Run `poetry run pytest` to ensure tests pass

Changes:

1. Clarified numpy upgrade is a breaking change (1.x → 2.x)
2. Listed specific version bumps for all dependencies
3. Documented the pie chart fix for numpy 2.x compatibility
4. Noted the changeset is correctly marked as major
