[mkdir] Args are in caps

[Tyriar]

Sanity checks

• My issue relates to a specific CLI completion spec (e.g. git checkout is missing options in git completion spec). If your issue is more general, please create your issue here: withfig/fig
• I have searched github.com/withfig/autocomplete/issues and there are no duplicates of my issue
• I would like to work on this.

What CLI tool does this relate to?

mkdir

Which statement makes the most sense?

There is a bug with this completion spec

Issue Details

Mode and context are in screaming caps:

autocomplete/src/mkdir.ts

Lines 10 to 28 in f8e94e3

	{
	name: ["-m", "--mode"],
	description: "Set file mode (as in chmod), not a=rwx - umask",
	args: { name: "MODE" },
	},
	{
	name: ["-p", "--parents"],
	description: "No error if existing, make parent directories as needed",
	},
	{
	name: ["-v", "--verbose"],
	description: "Print a message for each created directory",
	},
	{
	name: ["-Z", "--context"],
	description:
	"Set the SELinux security context of each created directory to CTX",
	args: { name: "CTX" },
	},

Would be best to be consistent here.
