Resolves https://github.com/safe-global/developer-experience/issues/400

[something](/something) => [something](./something.md)
[something](/something) => [something](./something.mdx)
[something](./something) => [something](./something.md)
[something](./something) => [something](./something.mdx)
[something](./something#somethingelse) => [something](./something.md#somethingelse)
[something](./something#somethingelse) => [something](./something.mdx#somethingelse)

Changelog

• Adds a script that checks all links follow the right format and finds all the ons that don't follow it.
• Updates all links to this format
• Fixes broken links
• Updates redirects

Dependencies

• This PR depends on fix(API): Replace v1 with v2 endpoints #735. Once it is merged this needs to be rebased and update the link [multiple networks](../../../core-api/transaction-service-supported-networks) that currently doesn't follow the new format, and regenerate the references.

Checklist

• I've followed all safe-docs pull request rules
