jsr: deno install cannot infer executable name from the jsr https url

[sylc]

Version: Deno 1.40.4

Providing a jsr address of a package, I would expect deno install to infer the name of the executable as the package name, in the above example dkill. Similar to the existing behaviour with an address targeting /x. for example https://deno.land/x/dkill@0.10.0/cli.ts

It seems to work for a jsr url.

> deno install jsr:@sylc/dkill@0.10.1
✅ Successfully installed dkill

For https specifiers, maybe if the folder is a version then it should check the parent folder name.
