Example Docs fixes (#6919)

Hello, 

As discussed with @sighphyre, there were a number of problems with the
examples docs. This addresses the most pressing ones, namely:

- Corrected the link to the Jira plugin
- Added deprecation warning to Jira Server pages
- Removed the incomplete markdown table at the end of articles, and the
references to it

-It’s common for teams to have a development phase, QA/testing, and then a production release. Let’s say the changes we’ve made in our Java project must go through a typical development workflow. The [Unleash Jira plugin](https://marketplace.atlassian.com/apps/1227377/unleash-for-jira?tab=overview&hosting=datacenter) can connect to your Jira server or cloud to create feature flags automatically during the project creation phase. As your code progresses through development and Jira tickets are updated, the relevant flag can turn on in a development environment. The next stage could be Canary deployments for testing code quality in subsequent environments to certain groups, like a QA team or beta users. The flag could be automatically turned on in QA and/or roll out to target audiences in production.

-## Common Usage Examples of Spring Boot Feature Flags
-
-
-We’ve compiled a list of the most common functions to call in a Spring Boot app.
-
-| Annotation | Description | Parameters |
-| ---------- | ----------- | ---------- |
-| [`@Toggle`](#toggle-example) | determines whether or not the flag is enabled | feature flag name (string), alterBean (string), variants |
-| [`@FeatureVariant`](#featurevariant-and-featurevariants-example) | targets specific variant to reference | variant name (string), variantBean (string) |
-| [`@FeatureVariants`](#featurevariant-and-featurevariants-example) | targets specific | Array of feature variants |
-
-
-### `@Toggle` example
-
-```java
-@Toggle(name="demo-toggle", alterBean="featureNewService")
-```
-
-### `@FeatureVariant` and `@FeatureVariants` example
-
-```java
- @Toggle(name = "background-color-feature",
-    variants = @FeatureVariants(
-        fallbackBean = "noBackgroundColorService",
-        variants = {
-            @FeatureVariant(name = "green-background-variant", variantBean = "greenBackgroundColorService"),
-            @FeatureVariant(name = "red-background-variant", variantBean = "redBackgroundColorService")
-        }
-    )
-)
