feat(CodeSnippet): allow copy button to be optional

[emyarod]

Closes #6499

This PR allows the copy button to be optionally hidden from single and multiline code snippet. For inline code snippets, a span will be rendered instead of a button

Testing / Reviewing

Confirm the code snippet variants without copy buttons appear correct

Functionality of showing and hiding the copy is working 👍🏻

When we hide the copy button for single and multi-line code snippets the padding on the left should change to allow more text to fill the empty space.

Spec:

[laurenmrice]

Inline code snippet
-The inline code snippet increases in height when the no copy button prop is turned on.

Single line code snippet
-The overflow text is getting a hard cutoff instead of having the gradient when you horizontal scroll.

[emyarod]

the inline code snippet height change should be resolved now

the gradient does not appear in Netlify because of CSS custom properties (related #4426) and this is not a regression in this PR. but I have implemented a workaround at the component level (#6410 for example) and I can resolve this issue for gradients in the other affected components in a separate PR

looks great! thank you 🙌🏻

LGTM 👍 ✅

@emyarod it looks like a border: none was removed. Was that intentional? Don't see anything referring to the border so just wanted to make sure before I approve the visual diff

[emyarod]

cc @laurenmrice to double check the code snippet borders (single and multiline since it looks like they are the only variants that import border styles and then override them)

[laurenmrice]

Actually yeah, now there is a border showing up on the single line code snippet. it needs to be removed.

[emyarod]

does it also not belong on the multiline snippet? if so we can change the default mixin styles since they're currently being overridden in both variants

[laurenmrice]

It doesn't need to be used for any of the code snippet types. @emyarod

[laurenmrice]

looks good! thank you 👍🏻
