This leads to the table of launch / attach options to be rendered as an unformatted blob instead of as a table. See https://marketplace.visualstudio.com/items?itemName=llvm-vs-code-extensions.lldb-dap This commit fixes the issue by completely avoiding escaped backticks in the README. While at it, I also fixed a couple of typos / small wording issues. Also, I reordered the ways to procure the `lldb-dap` binary in priority order: Most users should prefer the toolchain-provided binary over building it from source.
