Added Tabs for both near-cli-rs and near-cli commands

[ghimire007]

As discussed in #1478 tabs imports are fixed and Commands mentioned in near/near-cli-rs#236 are updated

@ghimire007 could you rename all instances of Near-CLI to near-cli? also please make sure to remove all unnecessary new lines. In general, you just need one blank line between code and a tag, i.e.:

code here

<one blank line>
</close tab>

And there is no need to have a blank line at the end of code:

code here
<remove-this-blankline>

After that I'll accept it and merge it. Thanks for the contribution!
