Remove unnecessary executable flags from Rust source files

[mamekoro]

Objective

I found that some .rs files are unnecessarily executable.

Rust source files may start with a shebang-like statement #!, so let's make sure they are not executable just in case.

Here is the result of the find commend that lists executable .rs files as of main branch 86bd648.

$ find -name \*.rs -type f -executable
./crates/bevy_gizmos/src/lib.rs
./crates/bevy_tasks/src/lib.rs
./crates/bevy_time/src/lib.rs
./crates/bevy_transform/src/lib.rs
./src/lib.rs

It appears that the permissions of those files were originally 644, but were unexpectedly changed to 755 by commit 52e3f20.

Solution

Make them not executable by using this command;
find -name \*.rs -type f -executable -exec chmod --verbose a-x -- {} \+
