fix: Stop SmartyPants from altering TerminalBlock commands (like --save-dev to —save-dev)

[smikitky]

This fixes #8140.

With this change, contents in <TerminalBlock> will no longer be processed by SmartyPants. Previously, -- was converted to en-dashes, so --save-dev looked like —save-dev (with an en-dash) unless each snippet was manually escaped using a hacky and nonintuitive syntax. This PR will prevent this type of bugs once and for all for contributors.

Before (current problem in https://react.dev/learn/typescript):

Change summary

• Edited the remark-smartypants.js plugin so that it no longer transforms <TerminalBlock> content. This is done by tagging its subtrees with data.skipSmartyPants and bailing out before running the typography pass.
• Render TerminalBlock output with <pre><code> instead of relying on generic <div> wrappers. This was not strictly necessary to fix the current bug, but I believe it's desirable.
• Clean up every existing TerminalBlock usage by stripping the hacky {`…`} workaround
• Bump DISK_CACHE_BREAKER

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
