Remove orphan account mocks not referenced by any guide

[ernestognw]

Summary

Two example mocks under contracts/mocks/docs/account/ are not referenced by any .adoc guide in this repo:

• contracts/mocks/docs/account/MyAccountEIP7702.sol
• contracts/mocks/docs/account/MyFactoryAccount.sol

They are referenced only by solidity guides (accounts.adoc, eoa-delegation.adoc) in openzeppelin-contracts.

Why this matters

scripts/prepare-docs.sh copies every contracts/mocks/docs/**/*.sol into the docs site's shared examples/ directory. Because the version of these files in this repo diverges from solidity's (different signatures, missing checks), every community-contracts docs regen clobbers solidity's canonical version and breaks the contracts/5.x guides.

Concrete example surfaced by docs PR #154: community's MyFactoryAccount.sol changes predictAddress(callData) → predictAddress(salt, callData), but the contracts/5.x/accounts.mdx prose was written for the 1-arg form.

Deleting them here keeps the canonical version in solidity and stops the regen pipeline from clobbering unrelated examples.

Test plan

• Re-run the docs regen for community-contracts and confirm examples/account/MyAccountEIP7702.sol and MyFactoryAccount.sol are no longer touched

Walkthrough

Two mock contract files are removed from contracts/mocks/docs/account/: MyAccountEIP7702.sol (an EIP7702-based account with multi-inheritance) and MyFactoryAccount.sol (a factory for deterministic clone deployment and initialization).

Poem

🐰 Two mock contracts take their leave,
Away from docs they now perceive,
The factory and EIP's refrain,
Cleaner code, a lighter chain,
Contracts gone, examples plain.
