Material-ui: [Breadcrumbs] Inconsistent "aria-label" instruction and example

[MalignantShadow]

The documentation section for Breadcrumbs state the following (under "Accessibility"):

Be sure to add a aria-label description on the Breadcrumbs component.

However, in the actual code demos for Breadcrumbs, the property used is "arial-label". Possible typo? If so, probably the result of copy/paste

• SimpleBreadcrumbs demo: Lines 29 and 41
• CustomSeparator: Lines 31, 43, 55,

• etc...

• [x] This is not a v0.x issue.

• [x] I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior 🤔

Code in demos should say <Breadcrumb aria-label="Breadcrumb">

Current Behavior 😯

Code in demos say <Breadcrumb arial-label="Breadcrumb">

Steps to Reproduce 🕹

Look at the code of any demo in Lab/Breadcrumbs

@MalignantShadow Yes, it's definitely a typo. We should be using aria-label in the demos. Do you want to fix it? :)
