Update typescript-coding-guidelines page (include section to use tslint-to-eslint-config)

[atrianac]

TSLint was deprecated as is described in Palantir blog post TSLint in 2019. On typescript-coding-guidelines page should include a section to promote the use of ESLint over TSLint.

Note: There is a specific package which use typescript-eslint build by adidas.
