Viash 0.8.2 (2023-12-14): Minor changes and bug fixes

This release fixes a few bugs regarding dependencies and how the Nextflow platform handles Paths.

MINOR CHANGES

NextflowTestHelper: Do not hardcode a version of Nextflow in the testbench,
but use the version of Nextflow that is installed on the system (PR #593).
GitHub Actions: Test different versions of Nextflow (22.04.5, latest, and latest-edge) (PR #593).
Testing the latest Edge version of Nextflow will allow us to catch notice changes in Nextflow earlier.
Updates to the documentation and templates in the Git repo (#598, PR #600):
- Add contributing guidelines.
- Add issue templates.
- Reworked the pull request template.

config: Fix the main level of a component config not enforcing strict mode and instead allowing any field to be specified (PR #585).
dependencies: Allow the user to define a local dependency with specifying repository: local as sugar syntax (PR #609). A local repository is the default value so it's not required to be filled in, but allowing it with a sensible sugar syntax makes sense.
Repositories: Fix a structural issue where a repository defined directly in a dependency would require the name field to be set (PR #607). Repository variants are created with and without the name field. Repositories under .functionality.dependencies[] use repositories without the name field, while repositories under .functionality.repositories[] use repositories with the name field.
NextflowPlatform: Do not resolve remote paths relative to the --param_list file (PR #592).
NextflowPlatform: Allow finding .build.yaml file when worktree contains a directory that is a symlink (PR #611).
