This commit rename the existing setting `Who can invite users to this
organization` to `Who can send email invitations to new users` and
also renames all the variables related to this setting that do not
require a change to the API.
This was done for better code readability as a new setting
`Who can create invite links` will be added in future commits.
Following the issue #23380 and PR #25038, this commit changes all
occurences of `uri` into `url` in all comments, local variables,
handlebars templates (.hbs) function names and their callers in
all `.js` and `.ts` files.
