Fixed typos.

These typos are catched by `misspell` program.

```
find . -type f | grep -v assets | grep -v dummy-data | grep -v i18n | grep -v node_modules | grep -v .git | grep -v apigen |  xargs misspell -w
```

Some results were excluded because of 3rd party ownership and non-english
sentences.
