chore: update deprecated workspace file log

[btea]

Description

I think it is more friendly to specify the specific level of the projects field in the printed log information.

However, I also wonder if some users will misunderstand test.projects as a field. Look forward to your opinions.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. If the feature is substantial or introduces breaking changes without a discussion, PR might be closed.
• Ideally, include a test that fails without this PR but passes with it.
• Please, don't make changes to pnpm-lock.yaml unless you introduce a new test example.

Tests

• Run the tests with pnpm test:ci.

Documentation

• If you introduce new functionality, document it. You can run documentation with pnpm run docs command.

Changesets

• Changes in changelog are generated from PR name. Please, make sure that it explains your changes in an understandable manner. Please, prefix changeset messages with feat:, fix:, perf:, docs:, or chore:.

If we want to use this style, it should be applied here too:

vitest/packages/vitest/src/node/core.ts

Lines 433 to 435 in c69be1f

	this.logger.warn(
	'Both `config.projects` and `config.workspace` are defined. Ignoring the `workspace` option.',
	)

vitest/packages/vitest/src/node/core.ts

Lines 448 to 450 in c69be1f

	this.logger.deprecate(
	'The `workspace` option is deprecated and will be removed in the next major. To hide this warning, rename `workspace` option to `projects`.',
	)
