docs: Two small typos in "What is Consul?" introduction

[beckilee]

Overview of the Issue

There are two small typos in the introductory What is Consul? documentation:

• device should be devices in the following sentence: Consul offers service discovery, service mesh, traffic management, and automated updates to network infrastructure device. (What is Consul?)
• discloser should be disclosure in the following sentence: Microservice architectures are complex and difficult to secure against accidental discloser to malicious actors. (Enable zero-trust security)

Also, hi! 👋 I'm a first-time contributor and I'd love to create a PR to address this issue, if y'all don't mind.
