fix(template-no-template-lint-directives): unquote rule names when converting

[johanrd]

Reported during an ember-template-lint → eslint-plugin-ember migration.

Quoted rule names are valid in both linters

• ember-template-lint maps its unquote helper over every name in a template-lint-disable / template-lint-enable list (_base.js). Verified against 7.9.3: {{! template-lint-disable "no-invalid-role" }} suppresses no-invalid-role, while {{! template-lint-disable "no-positive-tabindex" }} does not — so quotes really are stripped before matching, and this isn't the "no arguments disables everything" path.
• ESLint core unquotes too: /* eslint-disable "no-console" */ suppresses no-console, /* eslint-disable "no-debugger" */ does not, and /* eslint-disable "zzz-nope" */ reports Definition for rule 'zzz-nope' was not found — quotes already stripped in the message.

So this isn't an exotic ember-template-lint-ism being dragged into ESLint; both sides accept it.

It also occurs in the wild. A narrow GitHub code search for the quoted form in .hbs returns 16 files (a floor — code search only indexes public repos), including the official ember-learn/ember-website:

{{!-- template-lint-disable "no-forbidden-elements" --}}   ember-learn/ember-website
{{! template-lint-disable "attribute-indentation" }}       mirego/accent
{{!template-lint-disable "no-negated-condition"}}          burningmantech/ranger-clubhouse-web
<label {{!template-lint-disable "no-nested-interactive"}}> NYCPlanning/labs-streets

Problem

The conversion fixer passed the name through verbatim, so the ember/template- prefix landed outside the quotes:

{{! template-lint-disable "no-log" }}   →   {{! eslint-disable ember/template-"no-log" }}

That name is quoted in the middle, so neither linter's unquoting applies. Verified — it does not suppress:

Definition for rule ember/template-"no-log" was not found. | Unexpected log statement in template.

eslint --fix over a codebase using quoted names therefore silently converted working suppressions into dead ones, re-reporting violations the author had deliberately disabled. That is the exact failure this rule exists to prevent.

Fix

Unquote each name before prefixing, mirroring upstream's unquote semantics: strip only when the first and last character are the same quote character (single or double), so "no-log' and other mismatched-quote inputs still pass through unchanged.

Tests

Double-quoted, single-quoted, mixed quoted/unquoted lists, template-lint-enable, and the mismatched-quote pass-through case.
