Use reusable MDX template to DRY-ify the deployment tables

[PaulRBerg]

Problem

Page: https://github.com/sablier-labs/docs/blob/1959c2eeb5e4ca71e2ff65ff530b865ed9ec2c60/docs/guides/lockup/02-deployments.mdx

• Poor developer experience: the rows in the tables no longer fit on a single line
• There's a lot of repetition
  • Links like core-v1-2-0 are duplicated 148 times
  • The blockchain explorer is duplicated many times, too
• The first two issues combined makes this page prone to errors (when errors are made)

Solution

Refactor this:

| Contract            | Address                                                                                                               | Deployment                                                                           |

Into something like this:

import DeploymentTable from "@site/src/snippets/DeploymentTable";

<DeploymentTable product="Lockup" version="v2.0.0" chain="ethereum-mainnet"/>

And the DeploymentTable snippet would render the appropriate Markdown table.

If this doesn't work, we might have to build a React component instead of an MDX snippet.

Planning

This task should be implemented AFTER #300.
