feat: add a typescript project to validate configuration using moduleResolution=bundler

[tbouffard]

WIP

Notes

This reproduces the issue mentioned in #390 (comment).

$ npm run build
> build
> tsc
src/index.ts:1:35 - error TS7016: Could not find a declaration file for module 'bpmn-visualization'.
'projects/typescript-config-validation/node_modules/bpmn-visualization/dist/bpmn-visualization.esm.js'
implicitly has an 'any' type.
There are types at 'projects/typescript-config-validation/node_modules/bpmn-visualization/dist/bpmn-visualization.d.ts',
but this result could not be resolved when respecting package.json "exports".
The 'bpmn-visualization' library may need to update its package.json or typings.

1 import { BpmnVisualization } from 'bpmn-visualization';
                                    ~~~~~~~~~~~~~~~~~~~~

Found 1 error in src/index.ts:1

TODO revert this when process-analytics/bpmn-visualization-js#2972 has been merged

Suggested change

	"moduleResolution": "bundler", // this configuration requires to have types declaration in the package.json "exports" attribute
	"moduleResolution": "bundler", // this configuration requires to have types declaration in the package.json "exports" field

Until we have a released version of bpmn-visualization including the fix, we should exclude to build this project with the release version.
And restore it when the new release is available.

Closing, this reproduction project is going to be directly integrated in bpmn-visualization with process-analytics/bpmn-visualization-js#2972.
This will give faster feedback.
