Multiple targets failing on analysis

[reginaldl]

Hi,

I just ran buck2 targets -A --json //... on the repo and it failed right away on multiple errors, here's the first one:

Error parsing gh_facebook_buck2//docs/buck2_lab/greeter_lib
Error parsing: `gh_facebook_buck2//docs/buck2_lab/greeter_lib:BUCK`

Caused by:
    error: Parse error: unexpected new indentation block here, expected one of "\n", "(", "+", "-", "...", "DEDENT", "FLOAT", "FSTRING", "IDENTIFIER", "INTEGER", "STRING", "[", "break", "continue", "def", "for", "if", "lambda", "load", "not", "pass", "return", "{" or "~"
      --> docs/buck2_lab/greeter_lib/BUCK:16:1
       |
    16 |     rust_test( # @oss-enable
       | ^^^^
       |

I think it might be worth adding a github action to run builds or at least analysis on PRs.
