Fix CI build failures by updating nx.json inputs configuration

[nsheaps]

This PR fixes the CI build failures by updating the nx.json inputs configuration.

The issue was that the build task was using 'production' and '^production' as inputs, but these named inputs were not defined in the nx.json file. According to Nx documentation, all filesets have to start with either {workspaceRoot} or {projectRoot}.

Changes made:

1. Added a namedInputs section with a default input
2. Updated the build task inputs to use '{projectRoot}/src/**/*' instead of the undefined 'production' inputs

This should resolve the error: 'production' is an invalid fileset.

remove this block please, as well as the deprecated affected block above this

I've addressed your feedback by removing both the namedInputs block and the deprecated affected block. I also updated the lint inputs to use {projectRoot}//* directly instead of 'default' since we no longer have named inputs. The build task still uses {projectRoot}/src//* as the input pattern.

I've made additional changes to fix the remaining build failures:

1. Added missing tsconfig.json files to the github-to-graphite-button and graphite-to-github-button packages.

These changes should resolve all the build failures. The CI checks should now pass.

I've made additional changes to fix the TypeScript errors in the button scripts:

1. Added proper type annotations for the toolbar parameter in the addButton function
2. Fixed the RegExp match handling to properly check for null values
3. Added explicit type for lastPathname variable

These changes should resolve all the TypeScript errors and the build should now pass.

I've made one more fix to address the remaining TypeScript errors:

1. Added type casting from Element to HTMLElement for the toolbar elements

This should resolve all the remaining TypeScript errors and the build should now pass.
