some updates to minuteman and connecting path near alewife

Move abandoned railway tag to the only spot where there is actually evidence of it on the ground. Otherwise some small updates in the area

Remove a rail line of which there is no longer any trace.

update tagging I had done incorrectly previously

Deleting a way which seems to have no tags and is not a member of any relation
