Bootstrap: v5.1.2 Release

Highlights

• Temporarily patched a postcss-values-parser issue by rearranging our calc() functions that use negative numbers. This should restore the ability to import and compile Bootstrap's Sass in create-react-app.
• Added border-radius sizes to small and large .form-selects
• Added align-self: center to buttons for improved rendering in flex containers
• Fixed Collapse regression that prevented toggling between sibling children
• Updated JS Sanitizer to add sms in the SAFE_URL_PATTERN
• Improved docs around .img-fluid
• Added role="switch" to our form switches in our docs
• Implemented GitHub Issue forms to replace our previous issue templates.
