[BUG] v10.3.0 breaks codecov upload file

[atlasrealm]

Describe the bug

We are using the github action v.5.4.0 for codecov and saw all our uploads breaking since yesterday. After a lot of searching I saw that the cli version had changed from v10.2.1 to v10.3.0. We did not change any configuration on our side:

The problem seems related to the data format of our uploaded file, which is now all of a sudden containing a few extra lines before <<<<< network:

/home/runner/work/company-name/codecov.SHA256SUM.sig
/home/runner/work/company-name/junit-backend.xml
/home/runner/work/company-name/lcov.info
/home/runner/work/company-name/coverage-backend.xml
/home/runner/work/company-name/coverage-functional.xml
/home/runner/work/company-name/codecov
/home/runner/work/company-name/codecov.SHA256SUM
/home/runner/work/company-name/junit-frontend.xml
/home/runner/work/company-name/junit-functional.xml
<<<<<< network

# path=/home/runner/work/carbon-equity/carbon-equity/coverage-functional.xml
<?xml version="1.0" ?>

These lines are only present since yesterday, and all uploads that have the lines fail.

Could you please help me? Thanks.

EDIT: We've changed the cli version in the github action back to v10.2.1 and everything works again.
