Task is a task runner.

go-task/task support multile file name (Taskfile.yml, Taskfile.yaml, Taskfile.dist.yml, Taskfile.dist.yaml),
but this patch just support Taskfile.yml for now.

Reference: https://taskfile.dev/

The behaviour of projectile-ripgrep was inconsistent depending on
which package was being used. If the rg package was being used, hidden
files were included in the search, while if the ripgrep package was
being used, hidden files were excluded. This commit ensures that
hidden files are now consistently included, which is consistent with
the behaviour of other searches (like grep).

Add local overrides for the project type attributes test-prefix,
test-suffix, related-files-fn, src-dir and test-dir.  Add tests
for this new behaviour.

Update readme and projectile.el

This is to prevent projectile-replace from searching on very large files of a project (my Emacs hangs when projectile search on a 1MB Javascript library file, while I only wanted to search and replace on Rust code).
