Filtering workspaces based on tags fails if tag value contains ":"

[sharathrnair87]

If the tag associated with the workspace contains a : character , the workspace does not show up when that tag name is specified as a filter in WorkspaceListOptions

https://github.com/hashicorp/go-tfe/blob/main/workspace.go#L258

How to reproduce:

1. Tag a workspace with a value which contains a ":" for e.g. test:tag
2. Compose a WorkspaceListOptions struct with the Tags field as the aforementioned tag

Expected Result:
Returns the workspace with the test:tag

Actual Result:
No workspace returned

Closing this issue as I've been unable to reproduce it lately. Will open a new one in-case it resurfaces.
