Stop letting code cleanup steps fail

[emmyoop]

These steps to remove blank lines/spaces show errors in the output even though we want to ignore the errors.

dbt-release/.github/workflows/release-prep.yml

Lines 387 to 399 in 8b85295

	# this step will fail on whitespace errors but also correct them
	- name: "Remove Trailing Whitespace Via Pre-commit"
	continue-on-error: true
	run: |
	pre-commit run trailing-whitespace --files .bumpversion.cfg CHANGELOG.md .changes/*
	git status
	# this step will fail on newline errors but also correct them
	- name: "Removing Extra Newlines Via Pre-commit"
	continue-on-error: true
	run: |
	pre-commit run end-of-file-fixer --files .bumpversion.cfg CHANGELOG.md .changes/*
	git status

Add || true logic to the commands to stop the errors from propagating to the output as they are not true errors. Also remove the continue-on-error lines as they will no longer be relevant.
