GitLab for Jira app: update browser alert with new copy

Originally discussed in !81126 (comment 860426101).

With the rollout of OAuth authentication in the GitLab for Jira app, cross-site cookies will no longer be an issue. There are still, however, some limitations that users should be aware of. This includes the following:

• crypto web api is unavailable https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API#browser_compatibility

Note that any browser that GitLab officially supports is supported here. https://docs.gitlab.com/ee/install/requirements.html#supported-web-browsers

Possible approaches

1. Remove alert completely

Depending on wider GitLab best practice, we might be able to avoid showing an alert, and assume that the user is using a supported browser.

2. Update copy

Copy:

Your browser is not supported
You must use [a supported browser](#) to use the GitLab for Jira app.
