Fix grammar in repo create prompt (#5557)

* Use plural linking verb

While it looks like you could use "there's" informally, grammatically, it should be "are" since "commits" is plural.

* Omit "the"

I created a remote called "github" and got this prompt:

> Would you like to push commits from the current branch to the "github"?

Normally, the default name "origin" doesn't sound bad in that prompt,
but using the name "github" made the prompt sound like something wasn't
right to my American English-speaking ears.

Here are a few options.  Yes, I know English grammar sucks, to put it
mildly.  But, hopefully, the following options and explanations make
sense.

Get rid of "the".  This is the option I went with.  "github" acts as a
proper noun, so no determiner is needed.  If you substitute your own
name for "github" in the original prompt above, you get the same effect:

> Would you like to push commits from the current branch to "github"?

Add the implicit word "remote".  "github" now acts as an adjective and
"the" refers to "remote":

> Would you like to push commits from the current branch to the "github" remote?

Or, combine the two.  This last option relies on the fact that
instructions and manuals often omit definite articles because most
articles are definite.  See the [zero-marking][2] article on Wikipedia.
The original prompt already does this by omitting "the" before the word
"commits":

> Would you like to push commits from the current branch to "github" remote?
