Suggestions:

• I think it would be convenient to allow leading "v" in argument, so that 1.2.3 and v1.2.3 would be equivalent. I guess we will often forget whether "v" is needed or not :)

• There is a convenient way to replace text in file using fileinput module https://stackoverflow.com/a/20593644/3169754

• I'd relax search pattern for "bindingsVersion". Don't assume "var" (it may be on another line or be "const"), instead search for bindingsVersion = "..." with arbitrary number of spaces around "=".

• Let's log to console all command we run and actions like modifying file.

• Let's print errors to stderr instead of stdout.

• Let's use exit(1) when exiting with error.

Ideally we also need "-f" option that will forcibly override tag both locally and remotely. We can add it in this pr or create a separate issue.

It also would be convenient to automatically change directory to project root at start, to allow invocation from any directory. I think we can assume that the script is in project root and chdir to script's dir.

fixed everything except "-f" option

LGTM!
