[PATCH v3] docs: add git hash-object -t option's possible values

From: John Cai <johncai86@gmail.com>

The summary under the NAME section for git hash-object can mislead readers to conclude that the command can only be used to create blobs, whereas the description makes it clear that it can be used to create objects, not just blobs. Let's clarify the one-line summary.

Further, the description for the option -t does not list out other types that can be used when creating objects. Let's make this explicit by listing out the different object types.

    docs: add git-hash-object -t option's possible values
    
    For newer users of Git, the possible values of -t in git-hash-object may
    not be apparent. In fact the current verbiage under NAME could lead one
    to conclude that git-hash-object(1) can only be used to create blobs.
    
    Update the verbiage to make it clear the command can be used to write
    objects, not just blobs. Also add the possible values for -t.
    
    Changes since v2:
    
     * grammatical corrections in command documentation.
     * clarify -t text by specifying what "type" is.
    
    Changes since v1:
    
     * updated verbiage of commit message
