fix(search): remove duplicate isdisabled arg

[marissahuysentruyt]

Description

I noticed there were accidentally 2 isDisabled arguments passed to the action button subcomponent found within the collapsed search field.

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Validation steps

• Pull down the branch to run locally or visit the deploy preview.
• In the search/stories/template.js file, verify there is only one isDisabled argument passed to the nested ActionButton.
  • The line isDisabled && "is-disabled" has been removed from the customClasses object, in favor of passing isDisabled a single time to action button.

Additional validation

• Navigate to the default search field story page and toggle the isCollapsed and isDisabled args to true.
• With the TAB key, attempt to focus on the collapsed search field's action button.
• Verify that the blue focus indicator is not visible.
• Verify no visual regressions have been introduced.

Regression testing

Validate:

1. The documentation pages for at least two other components are still loading, including:

• The pages render correctly, are accessible, and are responsive.

2. If components have been modified, VRTs have been run on this branch:

• VRTs have been run and looked at.
• Any VRT changes have been accepted (by reviewer and/or PR author), or there are no changes.

Screenshots

To-do list

• I have read the contribution guidelines.
• I have updated relevant storybook stories and templates.
• ✨ This pull request is ready to merge. ✨

Because action button has an isHovered arg too, I figured it was ok to move the isHovered arg from customClasses up here.
