<sl-tab> not using border radius token

[mcjazzyfunky]

I guess, this line here

shoelace/src/components/tab/tab.styles.ts

Line 18 in d8644c9

border-radius: 4px;

should be

 border-radius: var(--sl-border-radius-medium);

Looks a bit odd if you use a custom theme which prevents border-radius wherever reasonable, but still on the tabs you see a border radius of 4px.

[Edit] ... and this line here

shoelace/src/components/checkbox/checkbox.styles.ts

Line 32 in d8644c9

border-radius: 2px;

should be:

 border-radius: var(--sl-border-radius-small);
