How can you set file permissions when creating a new file in Go?

You can set file permissions when creating a new file in Go by using the os.Create function and providing the desired permissions as an argument using the os.FileMode type. For example, os.Create("myfile.txt") can be used to create a new file with default permissions, while os.Create("securefile.txt", 0644) can be used to create a new file with specific permissions (0644 in this case). The os.FileMode type allows you to specify both the file's permission bits and its mode.
