Typos in Readme

[Boscop]

In the Readme, it says:

{
	"command": "rust_doc", "keys": ["ctrl+r", "ctrl+d"], "context": [
		{"key": "selector", "operator": "eual", "operan": "source.rust"}
	]
}

Shouldn't it be this?:

{
	"command": "rust_doc", "keys": ["ctrl+r", "ctrl+d"], "context": [
		{"key": "selector", "operator": "equal", "operand": "source.rust"}
	]
}

("equal" and "operand")

It took me a PR and nearly 4 months to fix a simple typo in the README.md file, I think that tells a nice story about how much time I can expend in my side projects :(
