Update linkify

[nwmac]

Contributes to rancher/dashboard#8067

Updates linkify to newest version (4.1.3).

Note the import for linkify changed - instead of linkify/string, there is a package linkity-string

To test:

• In a project in the local cluster
• Create a secret and add a description of test https://www.rancher.com
• From the secrets list, click on the secret just created
• Verify that the description renders as a banner and that the text has been linkified, i.e:
• Ensure that the link opens in a new tab
