Create .local/bin if it doesn't exist ("Could not find a PATH directory automatically" error)

[dot-file]

I've added /home/user/.local/bin to my PATH variable but was still getting this error:
Could not find a PATH directory automatically, falling back to manual selection

After reading the source code I found out it checks if a directory exists and is writeable in one go (config_unix.go:28):

err := checkDirExistsAndWritable(p)
if err != nil {
	log.Debugf("Error [%s] checking path", err)
	continue
}

This leads to the aforementioned error even if the PATH var is set correctly and it's just that the directory doesn't exist. As it's in user home directory I see no problem in creating it automatically. But if this is not the case, the error message should be changed because currently it's misleading.

I can make the PR myself (though I'm not really familiar with golang) but I just wanted to know if it's worth doing in advance.

hey yes, creating the directory if it doesn't exist SGTM!. I can kindly review the PR if you're willing to open it. We can also ask copilot here to give it shot if you don't have the time 🙏
