Corrected the sky130.json file, which had a major problem caused by accidentally duplicating a block of text, resulting in an invalid JSON file. Also: Revised the JSON file format so that "commit" is a block rather than a single key-value pair, and is contstructed similarly to the "version" block, with an entry for each tool used in the PDK build (currently magic and open_pdks), to provide a git commit number for each. This has to be done in conjunction with the update of magic to version 8.3.273 to provide the "--commit" command line option.
