A batch of docs style fixes.

docs/use_find_bugs_for_android.md

-# Introduction
+# Use FindBugs for Android
 
-[FindBugs](http://findbugs.sourceforge.net) is an open source static analysis tool from the University of Maryland that looks for potential bugs in Java class files. We have some scripts to run it over the Java code at build time.

-# How To Run
+## How To Run
 
 For gyp builds, add `run_findbugs=1` to your `GYP_DEFINES`.
 
 For gn builds, add `run_findbugs=true` to the args you pass to `gn gen`:
 
-```
-gn gen --args='target_os="android" run_findbugs=true'
-```
+    gn gen --args='target_os="android" run_findbugs=true'
 
-Note that running findbugs will add time to your build. The amount of additional time required depends on the number of targets on which findbugs runs, though it will usually be between 1-10 minutes.

-Some of the warnings are false positives. In general, they should be suppressed using [@SuppressFBWarnings](https://code.google.com/p/chromium/codesearch#chromium/src/base/android/java/src/org/chromium/base/annotations/SuppressFBWarnings.java). In the rare event that a warning should be suppressed across the entire code base, it should be added to the [exclusion file](https://code.google.com/p/chromium/codesearch#chromium/src/build/android/findbugs_filter/findbugs_exclude.xml) instead.

-  * Include a comment that says what you're suppressing and why.
-  * The existing suppressions should give you an idea of the syntax. See also the FindBugs documentation. Note that the documentation doesn't seem totally accurate (there's probably some version skew between the online docs and the version of FindBugs we're using) so you may have to experiment a little.
