Temporary files present in sources (qtdeclarative)

In the qt everywhere source tarball (5.12.11 & 5.15.2 & 6.1.2) , as well as on git, there is this file named #undefined-tobigint.js# which is equal to undefined-tobigint.js

Path: qtdeclarative/tests/auto/qml/ecmascripttests/test262/test/built-ins/TypedArrays/ctors-bigint/object-arg/#undefined-tobigint.js#

This may be a temporary file.

Could you remove it ?

It is also in git
