ref(replay): remove explicit tags[] bracket from tag panel links

[aliu39]

tags[""] is an older search filter syntax, used to explicitly indicate the filter is a custom tag. It might be used in other products' search bars, but we don't need it for replays. The backend interprets unknown filters as tags by default, in the code snippet here. If we wrap with tags[""] it is stripped here.

Right now:

1. list page > click search bar > select a tag suggestion: doesn't use tags[""].
2. details > "Tags" tab > click on a blue link to make a search: uses tags[""]. Example: https://sentry.sentry.io/feedback/?feedbackSlug=javascript%3A5900621324&project=11276

To reduce confusion let's not use this syntax for 2.
