docs(integrity_checking): improve clarity

I'm making this proposal for improving clarity of the language because I personally found the original phrasing a bit confusing in some places.

 Deno can store and check subresource integrity for modules using a small JSON
 file. To opt into a lock file, either:

 2. Use the `--lock=deno.lock` to enable and specify lock file checking. To
    update or create a lock use `--lock=deno.lock --lock-write`. The
    `--lock=deno.lock` tells Deno what the lock file to use is, while the
    `--lock-write` is used to output dependency hashes to the lock file
    (`--lock-write` must be used in conjunction with `--lock`).

 Like caching above, you can also use lock files during use of the `deno run` sub
 command, validating the integrity of any locked modules during the run. Remember
-that this only validates against dependencies previously added to the lock file.
+that this only validates dependencies previously added to the lock file.
 
 You can take this a step further as well by using the `--cached-only` flag to
 require that remote dependencies are already cached.
