ci(coverage): disable Codecov patch

[wellwelwel]

This PR doesn't change the previously defined coverage percentages.

Codecov initiates two tests (project and patch). The patch analyzes the percentage file by file, without considering the overall project context, which can cause CI failures even when the project coverage is in line with the established.

In order to maintain better productivity, this PR quiets the patch CI.

CI examples:

Example of PRs that would be less productive even with proper overall coverage:

• feat(pool): added acquireTimeout supports for pool #1919
• Adapt to Cloudflare Workers environment #2289
