Feature request: Ignore files on MD5 hash generation

Subject

We recently started using AWS CodeArtifact and in order to install dependencies using npm i or npm ci we need to update the npm config which, for our specific case, updates the local folder and includes a .npmrc. This makes the MD5 hash to always change resulting in longer builds.

I am currently working a PR that will add a new Task parameter to specify a set of files to be ignored from the MD5 has generation
