CodeCov badge shows "0%" in README

[exoego]

It shows 0% but actually 91+ %

I think a link to badge image has been changed.
Only Honojs member can get the URL from settings page:

This was fixed with the revert commit #4076

We should set up Bundle Analysis correctly. Related to #4072

But if it's difficult, I think we don't have to use Bundle Analysis since we are measuring the bundle size with the CI:

hono/.github/workflows/ci.yml

Lines 199 to 202 in f5ae405

	- name: Performance measurement of bundle check
	run: |
	bun run build
	bun perf-measures/bundle-check/scripts/check-bundle-size.ts > perf-measures/bundle-check/size.json

This can be fixed. Thanks!
