No Frame -> google error

# Bug Report

## Description

When adding a content element with option "no frame", the output looks like:

```

my content...

when checking a site with a content like that with https://pagespeed.web.dev, an error in the seo-chapter occurs:
"links cannot be crawled". See screeshot.

## Steps to Reproduce

1. Add content with option "no frame"
2. Test url with https://pagespeed.web.dev
3. See chapter "SEO"

### Solution

I think replacing the a-tag with an span oder div (in file https://github.com/benjaminkott/bootstrap_package/blob/master/Resources/Private/Layouts/ContentElements/Default.html, line 35) should solve the problem, as we don´t want an link there, but an possible link-target.

### Screenshots


## Versions

TYPO3 11
Bootstrap Package 12.0.5

Review Resources/Private/Layouts/ContentElements/Default.html at the referenced line and reproduce the issue by adding content with the “no frame” option, then checking the URL with PageSpeed Insights. Confirm that the generated markup no longer produces a crawlable-link error in the SEO report.
