refactor: move wdio.conf.ts to the project root

[jkoenig134]

@vobu as discussed this PR is headed to align the configuration of wdi5 tests with ts to those in js.

This is done by:

• wdio.conf.ts now resides in the project root
• specs laying in ./test/**/*.test.ts
• the file test/tsconfig.json is referenced for ts-node to compile the tests from ts to js using the tsNodeOpts in the wdio config

Next Step: Update the example ts-app in the wdi5 repo.
