fix: mark E2B_API_KEY as required for E2B sandbox tools

[thiagomoretto]

Summary

• E2B_API_KEY was declared with required: false on the shared E2B tool base (E2BExecTool, E2BFileTool, E2BPythonTool), even though none of the three tools can create or attach to a sandbox without it. This PR flips it to required: true.
• E2B_DOMAIN stays required: false — it's genuinely optional and defaults to e2b.dev when unset.
• Regenerated lib/crewai-tools/tool.specs.json by running src/crewai_tools/generate_tool_specs.py (not hand-edited) so the diff there is exactly the 3 required flags flipping from false to true, one per E2B tool.

Why

tool.specs.json is the machine-readable source of truth for tool env var requirements, and downstream consumers rely on the required flag to validate configuration up front. With E2B_API_KEY flagged optional, a missing key only surfaces at runtime when sandbox creation fails, instead of at configuration time. Since no E2B tool works without the key, the spec should say so.

Changes

• lib/crewai-tools/src/crewai_tools/tools/e2b_sandbox_tool/e2b_base_tool.py: E2B_API_KEY EnvVar entry now has required=True (single shared declaration used by all three E2B tools).
• lib/crewai-tools/tool.specs.json: regenerated via generate_tool_specs.py.

Test plan

• ruff check on the touched source file — all checks passed
• pytest lib/crewai-tools/tests/test_generate_tool_specs.py — 10 passed
• Confirmed no existing E2B-specific test file to update (none exists yet)
• Regenerated tool.specs.json via the real generator script (generate_tool_specs.py), not hand-edited, and diffed to confirm only the 3 expected required flags changed

Pull request overview

This PR corrects the E2B sandbox tools’ environment-variable metadata so downstream consumers (notably CrewAI AMP) can properly validate and forward E2B_API_KEY, which is necessary for creating/attaching to E2B sandboxes.

Changes:

• Mark E2B_API_KEY as required=True in the shared E2B sandbox base tool env var declaration.
• Regenerate lib/crewai-tools/tool.specs.json so the three E2B tool entries reflect the required flag change (and only that change).
