Code block: Add option to transform back to Paragraph

[annezazu]

What problem does this address?

Currently, one can transform from a paragraph block to a code block but, in order to transform back to a paragaph block, one must first transform from code to pre-formatted and then an option for a paragraph block appears. This was found as part of the sixteenth call for testing for the FSE Outreach Program:

Changing a paragraph into any blocks can easily be reverted back into a Paragraph Block, except when it is changed to a Code Block. While one can easily unwrap a quote back to a paragraph, or revert a pullquote, a preformatted, a verse, a heading, or a list back to paragraph block. The same effortlessness is gone once the paragraph is transformed to a Code Block. Here one is faced with unintuitive options to operate on the Code Block (quote, preformatted, group, columns, custom HTML). To transform the Code Block into a paragraph, it needs to be changed into a Preformatted Block first.

What is your proposed solution?

Add the option to transform to a paragraph block to the code block's transform menu:

The option to switch from Paragraph to Code was originally implemented here: #38295 The reverse just wasn't done :)

Happy to handle this one.
