Update webargs requirement from ~=6.0 to >=6,<9

[dependabot-preview]

Updates the requirements on webargs to permit the latest version.

Changelog

Sourced from webargs's changelog.

8.0.0 (2021-04-08)

Features:

• Add Parser.pre_load as a method for allowing users to modify data before schema loading, but without redefining location loaders. See advanced docs on Parser pre_load for usage information. (583)
• Backwards-incompatible: unknown defaults to None for body locations (json, form and json_or_form) (580).
• Detection of fields as "multi-value" for unpacking lists from multi-dict types is now extensible with the is_multiple attribute. If a field sets is_multiple = True it will be detected as a multi-value field. If is_multiple is not set or is set to None, webargs will check if the field is an instance of List or Tuple. (563)
• A new attribute on Parser objects, Parser.KNOWN_MULTI_FIELDS can be used to set fields which should be detected as is_multiple=True even when the attribute is not set (592).

See docs on "Multi-Field Detection" for more details.

Bug fixes:

• Tuple field now behaves as a "multiple" field (585).

7.0.1 (2020-12-14)

Bug fixes:

• Fix DelimitedList and DelimitedTuple to pass additional keyword arguments through their _serialize methods to the child fields and fix type checking on these classes. (569) Thanks to decaz for reporting.

7.0.0 (2020-12-10)

Changes:

• Backwards-incompatible: Drop support for webapp2 (565).
• Add type annotations to Parser class, DelimitedList, and DelimitedTuple. (566)

7.0.0b2 (2020-12-01)

Features:

• DjangoParser now supports the headers location. (540)
• FalconParser now supports a new media location, which uses Falcon's media decoding. (253)

media behaves very similarly to the json location but also supports any registered media handler. See the Falcon documentation on media types for more details.

Changes:

• FalconParser defaults to the media location instead of json. (253)
• Test against Python 3.9 (552).
• Backwards-incompatible: Drop support for Python 3.5 (553).

7.0.0b1 (2020-09-11)

Hi, I was about to lend a hand to this upgrade (I use webargs-starlette, but need a newer webargs version), but I am not seeing any errors when running my tests locally, and the failure logs are no longer available. Can the this branch be rerun and if no errors existing (which I believe is the case) be merged and released?
