[fix] rename dotfiles to avoid template problems

[Conduitry]

Fixes #2952.

Rather than adding another special case for .npmrc like there already is for .gitignore, this simply renames all dotfiles to instead begin with DOT- when the create-svelte package is being built, and un-renames them when bootstrapping a new project with the CLI. This doesn't currently handle dotfiles other than at the top level of a particular template, but we don't have any of those. I didn't include that for simplicity, but if other folks think that would be a good idea to handle now while we're thinking of it, I'd be amenable to that.

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. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpx changeset and following the prompts. All changesets should be patch until SvelteKit 1.0

I don't see the renamed dot-files in this PR

[Conduitry]

They're not renamed in this repo, and they shouldn't need to be. They're renamed as they're copied into the dist folder that gets packaged up, and then renamed back by the CLI when they're copied to the user's directory. Try this out locally and examine the contents of npm pack and the results of running the CLI.

Ah now I understand, thanks!

LGTM

Maybe use regex here too, for the off chance that there will ever be any file containing DOT- in it's name...

Suggested change

	copy(`${dir}/assets`, cwd, (name) => name.replace('DOT-', '.'));
	copy(`${dir}/assets`, cwd, (name) => name.replace(/^DOT-/, '.'));

[dreitzner]

DOT- could also be extracted as constant into packages/create-svelte/utils.js

I didn't review, but with four approvals, this seems safe to merge 😄
