fix(amazonq): Remove the 'Cancel' button on LSP download (aws#7184)

Just remove the 'Cancel' button for now when downloading the language
server. We do not want to deal with the edge case of a user cancelling
part way and then their Q features don't work since it depends on the
language server.

TODO: Figure out a better solution for allowing users to cancel the LS
download, but then making it easy to download again if they eventually
want it. We will also need to design it so they are aware that
cancelling will prevent Q features from working.

This will require an update to the spec.
