Make BUILDEVENTS_FILE an absolute path

[sargunv]

Often times I run a script via buildevents cmd in a directory other than my workspace root, but the command doesn't find the buildevents.txt file because the value of $BUILDEVENTS_FILE is ../buildevents.txt. It should be an absolute path instead by default to allow easily using this from any working directory.

Thanks for the report! We should be able to set this to an absolute path without much issue. We'll just have to figure out a good path.
The default value is set here: https://github.com/kvrhdn/gha-buildevents/blob/70cba094455143d466a64779533131eb1b28e105/src/buildevents.ts#L36-L37

Could just replace it with envPath = path.resolve('../buildevents.txt'). That way we'll use the exact same path we're using now, and work just fine with custom runners with their own file structure.

I'd be happy to PR this tomorrow.
