⚡️ Speed up function _posixify by 5%

[codeflash-ai]

📄 5% (0.05x) speedup for _posixify in src/click/utils.py

⏱️ Runtime : 915 microseconds → 871 microseconds (best of 152 runs)

📝 Explanation and details

Certainly! Here is an optimized version of the given Python program.

In this optimized version, converting the string to lowercase using .lower() is done before splitting the string using .split(). This makes it more efficient since it reduces the number of intermediate string objects created.
